1. What is the target audience for this site? (Its not 'hacker kinda' as mentioned in a comment here). Building that initial user base might be the key to the success.

2. Related to point 1, what is the 'essence' of the site? As in what kind of posts are allowed/not allowed, comment etiquette, is there any moderation? (Right now i see 'Bomb' blasts in India' as the top link. Incorrect headline, and and conveyed an entirely wrong message to me at least.)

3. For some reason the create login page didn't give me focus on the text boxes. (Firefox 2.0.0.16)

4. I was on a profile page, but did not get automatically logged on after creating the account.

The good part is you prefer the minimal and simplistic design. Good luck with your venture!

p.s. There was a 'pg' id on the site as well. :-)
