Twittervision is probably the biggest time suck I have seen online in a long time. After watching for 5 minutes you can't help but think "this is the biggest waste of time I have ever seen" and almost at the same time "this site is so fracking cool". Eavesdropping on the tech literate in the 21st Century and they are waiting to tell you their thoughts. The slice of life all around the globe mashup is very cool and probably addictive. If Evo hadn't warned me to have time to waste when I looked at it, I'd be plotting his demise right now, but since he warned me I'll forgive him. Have a half hour to waste check it out, if you don't don't bother.
