Twitter is about to add to the world's store of instant messaging apps. All Things D reports the avian-themed social network has considered a standalone messaging tool that would allow people to exchange 140-character missives that don't appear on their Twitter timelines.

BSD's "talk" still works, and has been useful since 1983.
Nothing new under the sun ...
 "talk" existed long before that, but it wasn't until 1983 that it became useful.

Twitter manages to explore new depths of pointlessness.
140 character limit on IM?
What? It's bad enough with tweets being limited to 140 characters (still..) and while that may have been part of the charm it quickly became annoying to me. I know there are alternatives and services such as TMI and TwitLonger but they feel like sticking an extra piece of paper to the bottom of an essay when you ran out of room.

Me: hey, you up for <popular activity> later?
Them: sure. what time?
sponsored IM: looking for a new boiler? we can help and we do insulation too!
Both of us: wtf?

Me: I'll call you...

Heavens knows you can't live without one for your SMS.
So twitter starts as an SMS based service, limited on characters due to the protocol it runs across. Anybody could use SMS, but they used twitter to be social.
Now you can use it for IM? But everybody had that to start with.
