I've run into this problem with all kind of sites. I would imagine at least one of those sites would of had a good idea in them. More recently, I've made a stock trading website. Whenever, I talk to anyone who was/is a stock trader they love the site and think its a great idea. The problem is how do I get that group of people to the site to begin with.

You seem focused on whether the site is a good idea. That doesn't matter. It only matters whether the site is useful. If it's useful, you can tell one person who will then start using it regularly and telling their friends. If it's not useful, make it useful.

Why not just go ahead and link the sites you wish were more successful, then we can probably be more helpful.
