To all of us hooked on to the fancies of Twitter, look at the new perspectives that Mahesh brings to the table:

Conduit for Text Commands
Enter Twitter that does both the above tasks brilliantly. Twitter acts as a conduit, a passive conduit, that makes it perfectly suited in this scenario. It is this facet of Twitter that multiple services like IWantSandy, RememberTheMilk, etc build upon.

Advantages of Stripped Down Interaction Modes
This way of interacting with the service might not be everyone’s cup of tea but it has significant advantages.For example you can i) Add twitter bot as a contact in your IM and send commands to the bot. No need to sign onto any application. Anywhere you can have a IM client you could use this feature.
