Same. I think we need some way to coordinate the initial burst of content for some of the smaller subs. I hate to say it, but maybe we need to assign "homework" - Request (not require) new subscribers to contribute unique stories or info relevant to the mag/comm on some type of schedule.

Something like:
"As we try to grow this new community, we want to hear from you. We're asking (not requiring) all new subscribers to start a new post within their first week covering some aspect of the topic they find personally interesting or that they feel could help others. Just add "(1P)" to the title of the post. It doesn't matter if it's something you said elsewhere, if you're new to the entire topic and just want to post a bunch of questions, you have a funny story to tell, or have a super niche specialty.

Also, we should consider having more moderator-level users in subs to reduce the burden of moderation. It's more daunting if you're asked to be one of 3 mods than it is to be one of 15. We should also look into incentivizing moderation duties, but there's probably a much longer discussion to be had about that.
