Do you think tone down the email newsletter subscription boxes? I get it on the main page, but it is rather obnoxious to get it on an article, and then again when you go back to the main page and again on the next article. I do like the small news story bar that pops up on the top. It's there without being obtrusive.
I have a similar gripe about the redundant "share" bar that shows up on the bottom of the screen now. Why not just make the "share" bar that was already on the sidebar scroll with the page?
I do like the new forum interface overall, I just find that the two gripes above find me skipping the main page and its articles (and advertising) and going straight to the forum.
