(formerly TweetSpeak, changed as to eliminate confusion with TweetSpeak.com)
While I’m fond of the Twitter-as-water-cooler metaphor, there was something missing.
Namely Twitter is quiet, and offices are filled with loud, distracting chatter.
If you’re on a Mac you can now remedy this issue with TwitterCooler.app.
TwitterCooler downloads your friends tweets and reads them to you using the Mac’s built-in voices (selected at random).
Hey it’s Friday, you weren’t planning to get anything done anyway. 
Definitely going to have to give this a try!
Running as an app, how do I customize to only download tweets from my friends?
I’m getting into Twitter a lot these days.
