I would question your focus on growth. Yes, we all want this place to succeed. But do we really want this unlimited growth like Facebook, Reddit and all those other companies? Small communities are great, they give you a connection between users, they spark friendships and great discourse. Those are great. Yes, they are smaller than those multimillion user subreddits, but we’ve all seen those big subreddits slowly burning down. Dying to bots, to marketing spam, to low effort, popular comments, to reposts, to karma farming, to US politics. We’ve seen subreddit after subreddit dying to moderator burnout - because big subs are really hard to moderate, people will burn out. They are sacrificing their free time to deal with trolls, shills, putins guys and receive no compensation for that.

So maybe … let’s don’t replicate Reddit? Let’s focus on creating small, helpful communities and people will come.

You should remove old posts & comments from every site you post to on a regular basis. There is no reason for those pictures from 2007 being on Facebook. Your old Twitter comments from 2011 might bit you in the ass in a few years. Nobody in their right mind is looking at your 2014 Instagram posts and you don’t want people out of their right mind seeing those. Why should that comment about Obamas election still be available for the world? Just nuke your old stuff on a regular basis - nobody looks at it and if people are searching through your old posts, they want to harm you.
