The thing is, it isn't for chatting, it's for drawing. And you could just as well hang out in fan art on the forums if you wanted to critisize pictures!
There is no real community in Oekakis, just people who draw and comment. It can't keep a site together, at least, I think. :O
And yes, finding your niche is important. I always hated it when Ifo und a site that had news and info that I could just as well get somewhere else. If they had other stuff, well, OK, but it should be unique. No 'Raise a Pikachu' game, or 'Catch a Pidgey', you didn't make it.
For example, on my site, Ihave POkemon theories, explaining thigns like why Feebas only live in 6 tiles and why Electrode explodes at the slightest shock. I have fun things there. Personality. And that's rare nowadays.
I liked this guide so much, I posted a link to it at another forums, with credit, of course. hopefully, more people will read ut. <_<;
