The problem with using OS X Messages, Twitter, Facebook, and other communication clients is that they operate in separate locations. I got like five different ones open on my desktop right now and it’s a confusing mess of switching windows and tabs and errant messages.
To make life easier one clever hacker figured out how to add a Twitter Timeline to OS X’s Messages app so that you can read your entire Twitter stream, in realtime, from the Messages app. It’s awesome, and I want it now!
