I like it too. I might even use it, if there are enough high quality participants.<p>I read the whole Theory page and it struck me as blah blah blah blah blah, <i>except</i> for these two points:<p>1. Conversations on topics you want, going on right now;
2. Karma keeps the quality high.<p>To me those are the core, and they're a pretty cool core. If I were you I'd strip everything else out. And emphasize those two things on the main page.<p>Personally, I'd drop the recommendation system, or at least drop talking about it. There's so much tripe surrounding that kind of thing that, when I read it, I noticed that your credibility instantly dropped in my mind. I'd rather you put your effort into making it really easy for me to browse/search what's going on so that I can make my <i>own</i> choices. Recommendations won't make me want to use your site if there isn't a lot of value there already. And if you do develop a kick-ass way of recommending related stuff, don't talk to me about it, just show me a few suggestions unobtrusively and I'll eventually catch on.<p>I also like the slogan "chat rooms that really work".<p>Edit: on reflection, I seem to notice a pattern which, if it really is there, I suggest you avoid like the plague. It is the idea of the system being "intelligent". It comes out in details like your choice of the word "Theory" and the title of this post, as well as in the emphasis on the recommendation system and its overtones of AI. To me this is a big turn-off. I don't <i>want</i> a chatting system, and I certainly don't want an "intelligent" chatting system. What I want is intelligent conversation. It seems to me you've got the kernel of something that could actually offer me that, which could be genuinely valuable. Focus on that and try to get the system <i>out</i> of the way.<p>Edit 2: while it's fresh in my memory... I noticed another thought going through my mind which was, "I wonder who is on here that I know from somewhere else", like HN for example. I wonder if people would be willing to link their user names to their names from other communities. I would, if I knew that lots of other people from HN were talking about stuff on your site.
