The world seems to be all a Twitter. Even though Twitter has some of the worst downtime of all our must have services. How much downtime will it take before we say "Enough!"

The growing list is at: Twitter: A Twit Twit here and a Tweet Tweet there...
As ever, you can d ekivemark me on Twitter with your suggestions to add to the list.
