Just a few comments:

1. Just one menu please: Please put all the menu items in a single menu on the side or at the top of the page. The menu should be the same no matter where we are in the site.
2. Be careful with the rollovers. The current link rollover that changes the text to bold is annoying because sometimes the link moves down a line and the mouse cursor is no longer on it.
3. Keep the site light-weight. Believe it or not, some of us still have dial-up connections at home. The U.S. is dead last (or close) in broadband availability per-capita so it is pretty likely that I am not the only one.
4. Add a tagging capability to articles. See del.icio.us if you don't know what I mean. This would be the natural evolution of the current briefcase feature (which I like very much).

Overall, I like the site as-is and would be happy with it if there were no changes at all. But, since you asked... This is the best SQL Server community and I appreciate all the work that has gone into making it so great!
