You want an honest answer, Jacob? You're competing with a 17-year-old kid who made this web site for fun. I think you're taking yourself a bit seriously, and that's not a good thing.
Are you having fun with making it? Make it, then. Make a damn good web site. If it's damn good, people will use it. You can make this a damn good web site, right? It's not going to be a shitpile? I'm asking seriously, not rhetorically. Generally quality is more important than anything; if you've got it, you're set.
If you're not making it for fun, then frankly, I don't know why you'd have bothered to start in the first place. You don't think you're going to get rich off something like this, I hope. If you're learning something by making this site, you can still learn by making.
Or did you do it just to see the results? Because you can see the results on ChatRoulette. If you think you can do better, stop asking us if a better product will be worth anything and start asking yourself if you can really do better. If it's better, in a way that people care about, they'll use it. If it's not, then nobody will even care enough to mock you.
Are you doing something meaningful with your time? Answer honestly. If you are, then I can't see why you'd ask us anything of this sort. If you're not, then get yourself together and do cool shit.
