TweetUp for a cause: Vancouver tweeters hit Downtown Eastside

It started as a two-line message on the Internet and ended up mobilizing a small crowd that roamed Vancouver’s Downtown Eastside in the snow Sunday handing out warm clothing to the homeless who live there.

In a snow-covered demonstration of the power of social media, users of the online micro-blogging site Twitter — some who didn’t know each other in real life — searched in closets for clothes to hand out in the freezing streets.
