Need to save two characters in a tweet? You could rework your wording a bit (change “people” to “ppl” or “for” to “4” for example), or, if your tweet includes a link, you could turn to a shorter URL.
Bit.ly, Twitter’s default shortener, is already plenty short, but if you want the same experience in two less characters, you can now use j.mp, which appears to simply be bit.ly rebranded with a new URL.
First spotted over on Business Insider, it initially appeared that j.mp was integrated into bit.ly’s interface (see this screenshot), but now, it looks like it’s actually just a separate domain with the exact same features, including its own bookmarklet and sidebar. However, you can login to j.mp with the username and password that you use on bit.ly.
