While my vote says no comment, I'm going to comment anyway.
I am not happy with the changes. I see that your posted topics and hot topics came back after implementation; had they not, a 0 would have been scored. But, for threads I've posted in, I want a different color to know I was replied to. (The color scheme is another issue I have, but that should be fixable with skinning.) And in hot topics, I don't know how many posts there are, how many unread there are, who started it, etc. There's too high a loss of information in these sections.
I don't like the wall changes. As a place to communicate with others, they worked fine. But I don't care for a wall showing a game has been rated, that they posted to someone else's wall (which then needs to loaded seperately if you do care), and all the other stuff that feels like noise. And then there's the feed, which is a merger of everyone's wall. That's a disaster, not to mention the delay in time it takes to load it. It makes the site feel more like other sites that I don't care to use, and, well... don't!
Then we have the split pages. I recall before the split, that there was some talk about the credibility of VGChartz at some outlets. While I don't question said credibility, I think the splitting of the site into more sites with the "cool" spelling detracts from any professional look. (Not to mention the less intuitiveness of the new names...) Some of us, myself included, liked how these features were well tied together, even if we didn't necessarily use them all.
Finally, there's a few little things on both sides of the aisle. The organization of the game collections is better, but less convienent for me, as I would use my collection link here when shopping for games, to prevent duplicates. When posting on someone's wall (or updating your own status), enter seems to default now to logout. When posting to a thread (using a reply or quote button), you can not reference anything else in said thread, as it's all covered up. (I really did like the last 15 posts part of 2.0.)
Sorry, but overall, I see far too many negatives. And I'm also in the camp that release should have been delayed to iron out some of the bugs that have been ironed out already. With the number of regular people who have cut back in viewing, I personally would have held off until after E3, since I do think a fair number of us dissatisfied people will go elsewhere for the live feed now. I'll see how things will play out in the future, but I'd be lying if I said I feel optimistic...
