that's not entirely true, the amount of time any of us spends online looking at tech news is finite, therefore as the pie gets bigger some of the online communities shrink their viewership, have less participation and less engagement. So the idea of competition is actually quite valid. It's like saying there's room for Facebook and Google+, while that's true there definitely are winners and losers because user engagement in a community is a function of its health and status.
I applied for lobste.rs, sending an 8 paragraph email about myself, the admin didn't even take the time to reply to me, which I find extremely rude, if I am too lowly for his application, then letting me know how to improve would really have been polite.
As it is, because of how I was treat by them, I have an extreme aversion to this website. I don't see it as competition for HN, I was merely curious about the community there and it's comparison to the one here.
When did you send it? I don't know about the recipient of your email, but it's not uncommon for me to have a multi-week backlog of email. Long emails tend to get a long reply, so those take even longer.
Yeah, it's invite only too, so the idea is, you lower yourself and apply or you get invited by a friend because they like you.
So the end result is either it's full of really friendly, intelligent, hand picked people, or it becomes a clique full of friends who are less than intelligent.
