I still can't settle on a browser. Yesterday, Firefox started being unable to successfully upload to Vimeo. Chrome worked, but I have other irritations with Chrome. Meanwhile, on Windows, I was trying to browse an intranet site at Cincom, and getting a 500. Call Helpdesk, ask other people, no one else has the problem. I fire up Windows in a VM, try it there - works fine. So apparently, IE got a transient 500 response at some point , and then helpfully cached it for me.

These tools all stink, just differently :)
