Twitter's Biz Stone on the Colbert Report

In response to the readers request, here is the video of Biz Stone, co-founder of Twitter, on the Colbert Report of Comedy Central about why we twitter, who twitters, and where Twitter is going.

That's what he said exactly: "We are recognizing the differences now between profit and value... Right now, we are building our value. That means we are expanding our service worldwide."

I have heard complaints from Twitterers that the website's service has become instable recently. Maybe expand your bandwidth first?
