It really does take a long time to build a user base. I put up my site over a year ago. Actually - it will be 2 years next march. and I only have 52 registered users. and out of that only about 7 have more than 5 posts to their name.
It just takes time - and you have to have decent content for people to want to visit your site. That probably explains why mine has grown so slowly

but the point of mine was never to be huge. It started as a place for all of my flying buddies out here in Georgia to post videos and be dumb. We have a bunch of friends now out of state and even out of country. It really is alot of fun and it goes to show just how cool the majority of RC-ers are!
