Update 8/15/09 2:15pm EDT: Seems to back up and working now.
Twitter isn't working yet again and what a pain in the rear. Here's a screen capture:
I was in the middle of an interesting conversation with top enterprise blogger, Francine McKenna, and a writer for New York magazine when Twitter just stopped working. Although the writer was looking for conflicts of interest among enterprise bloggers, she was barking up the wrong tree in her search. Unfortunately, we never reached a point of resolution when Twitter crashed.
I'd link to the thread, but since Twitter is down, that just ain't possible.
