TwitterBar 2.4 was released this morning, and the main change is that it now integrates the URL shortening service tweak.tk. The URLs that .tk generates are the shortest you can get, weighing in at 15 characters; TwitterBar’s previous URL shortener, is.gd, generated 18-character URLs.
What does this mean? Well, now when you post a URL to Twitter with TwitterBar, you have 125 characters for your message instead of 122. So feel free to toss an extra LOL or BRB in there; you’ve got plenty of room.
