I really don't like it.
Before you had the sense that it was a mature, well coded website.
This to me feels like a thrown together forum based on some open source CMS.
I stress FEELS like, I know it isn't, but it's lost something as far as I am concerned.
There's no formatting of text, no emoticons (I think they are very important to allow you to show the tone of voice you were using when you typed, if you know what I mean ... wonder if they just work ;< )
Do the code tags work?
printf("Testing, testing, 1.2.3...."\\n");
On the whole, I would vote for the old site back.
