Way to post Twitter updates through IM

As suggested on the get satisfaction site I tried Ping.fm for updating my Twitter and Facebook messages.  This is quick and easy way to update Twitter.

Since many months the IM feature of Twitter is down.  I used to rely heavily on that feature.  Even if some features like direct messaging and receiving tracked updates are not available with Ping.fm it alteast provide a facility to post updates through IM.
