Broadcasting, or not broadcasting (Twitter and collegehumor.com)

I saw this post from Pragmatic Marketing last week, but wasn't able to watch the embedded video until the weekend because collegehumor.com is blocked by the corporate firewall.

See more funny videos and funny pictures at CollegeHumor.

The video illustrates the way in which Twitter conversations can often be one-sided affairs, without any effort to engage (especially the last "tweet," in which the guy doesn't speak to the woman right next to him).

The inability to watch the video illustrates the way in which many conversations can often be zero-sided affairs, without any opportunity to engage.
