ioi,
I am a frequent reader, seldom a poster, but I thought I might be able to add some insight from that perspective.
www.vgchartz.com is bookmarked on my browser, and when 3.0 launched I was lost. I didn't know where the news stories, and reader posted threads had gone, and I wasn't too interested in surfing from site to site to find them...although I still did (just not as frequently).
Thankfully (for you) I kept the original vgchartz.com bookmark on my browser toolbar, and continued to click on it daily. Now that the vgchartz.com portion of the site looks more similar to what I was accustomed to, I am able to browse to the stories of interest.
I think the changes you made are for the good when looking for new users, but I believe each portion of the site(s) are fragmented, and the current user base found the portion of the site(s) that interested them and likely bookmarked that site as vgchartz. You need to find a way to ensure that vgchartz.com is the jumping off point for current users.
My $0.02...hope that helps.
Now if you could just make if so I could click on the outer portions of the site for scrolling purposes, WITHOUT being taken to a site to order shirts, I'd be happy!
