Development on Itsy stopped when Twitter became hostile towards
3rd party developers as it transitioned its focus to Wall Street.
As of this writing Itsy still works, but at
some point it will quietly cease to load tweets and will then be silent forever!
A small simple Twitter app for Mac.
Itsy won't hog up your screen or do other crazy things.
