Well I just don't see the need to twitter, but I may be to old for that
In all honesty, I don't twitter in the sense everyone else does. Twitter can be used for other things. Since Twitter can be made private to only allow certain people (or no one) access to your Twitter's it can be used as a free SQS (Simple Queue Service). Companies like Amazon charge for this service, but for non-critical or experimental purposes, this is a nice alternative.
