'Chuck' flash mob adds Twitter

Update on the "Chuck" flash mob plans. The group hosted by ChuckTV.net is adding a Twitter component so that fans who aren't near the participating cities (or may be busy doing other things, like working) can play along.

The plan is for "Chuck" fans to Tweet their support for the show between noon and 1 p.m. PST in your local time zone on Monday. Multiple Tweets discouraged.
