Blogger has improved its performance by leaps and bounds over the past few weeks. Kudos to Jason, Steve, John, Eric, Graham and the rest of the crew. The only hitch I'm experiencing now is that I can't post in Safari (the Mac browser), so I'm posting from my PC. Unfortunately most of my 250+ bookmarks are on Safari, so it's a little harder to navigate.
UPDATE to this Update: It looks like the problem has been resolved. I'm making this edit from my Mac.
