Looks very nice. The lack of symmetry in the three white boxes at the bottom of the home page is... not quite annoying... but now that I know it's there I notice it every time.
Other issues/total personal opinions:
http://www.overlandjournal.com/journal/ shows seven clickable OJ cover icons in one tall column, all of which link to "http://www.overlandjournal.com/journal/current_issue"; meanwhile, the two columns to the right are a single icon each - the first column's extra covers seem superfluous.
Interestingly, this only happened the first time I accessed - Minutes later it was fine, so it may have been an isolated incident.
The "store" link takes you directly to the "back issues" category within the store. It took me three trips to realize there were other categories within the store.
"Blog" opens up in a new window. I assume this was intentional, but you never know.....
I really like the new format. Very elegant and readable. I am using the latest stable build of Firefox on a MacBook (1280x800) with Snow Leopard.
