I am LOVING this, and I can't wait to get home tonight when I can take more time to poke around. Wow!
I do agree with the comments about the avatars being on the right. I prefer to see the name of the poster first, starting on the left, and then the text of his or her post. It's just not what people are used to and we do read from left to right whether it's on paper or on a screen (at least, in English, that's what we do). However I could live with it if it's not changed.
I do like the avatars being all the same size. I know that sizing isn't always easy so we had mixed results, but it makes it easier to read.
And a huge thank you for the WHITE BACKGROUND with black text!
This is excellent. I am nearsighted (meaning I can see up close and don't use reading glasses) but I still hate to read or post on u2.com because of their poor design choice of red type on a black background for their paid members section.
The home page looks great too!
