You need to be active with your site, so many people think they can throw up a website/app and the community will run itself, it really doesn't. You've gotta be hands-on and engage with all the members, listen to them, especially over small things (what's nothing to you is a potential deal breaker for them) You gotta post, keep the discussion going, start the discussion etc. Reasons I've seen communities die 1, incompetent/not bothered admins and 2, micro management. So many admins become mini-Hitlers when they have a little bit of 'power'. Most importantly though is community, your users will stick with you through the worst buggy code so long as you show that you care about them.
