1. Hmm, I don't have a web site, but I do have a facebook account
. I used to have a web site (and I used to blog a lot more, and my profile used to be much more informative) but my parents would constantly comment on it and wouldn't give me any peace and quiet.
2a. Oh, you're the Arvind that did the GTKBoard project? I thought it was an interesting idea, but the code seemed unmaintainable and although I really wanted to contribute, I was having serious computer hardware failures and had to reinstall OSs every week or so. Really cool idea, though, and the new release is kinda fun too! :-)
2b. True, there's a lot of competition (e.g. Yahoo, Pogo, ICC, PlayChess, and others). I was imagining something similar to (but certainly not the same as) the old US Chess Live server. I'm aware that their business model didn't work for them, but they had some good ideas as far as the actual service went.
2c1. I have a few (very different) ideas for the front end that share some common characteristics (that distinguish it from the competition).
2c2. I would imagine interface-embedded (not pop-up) advertisements being the major source of revenue and a nominal fee, if necessary (but hopefully not). I'd hope that an entirely ad-based model would attract more users and would also be feasible from the business side of things.
Anyway, I know at this stage it's just an idea and even as an idea it's hardly complete, but feel free to bounce some ideas back and forth, and keep us posted if you've got other cool ideas too!
