Is it me you're looking for?

Clearly it hasn't been as long for everyone.

As Twitter's Chief Architect, Blaine Cook caught the brunt of the Twitter community's frustrations over the micro-blogging service's frequent downtime. He left the company earlier this year and has now joined Yahoo! to work on a service called FireEagle, apparently similar to Twitter but focussed on user-location.

Twitter's issue was a popular service which struggled to scale. Yahoo! already has scale, but struggles with services that offer value. Perhaps this is a perfect fit?

(By the by, if you're on Twitter, so am I)
