A new service offers to post voice files to Twitter, enabling those who can't even type 140 characters to contribute to their valuable insight to the blogosphere.

The service comes from Kirusa and, unlike competing services, doesn’t bother trying to transcribe the recorded voice but simply posts a recording of the message onto its web site and a link to the user's Twitter feed. But at least the company isn't trying to charge for the service.

The company reckons that using voice is much safer than trying to write Tweets while driving. We'll leave aside the various existing transcription services to ask why one would feel the need to post to Twitter while driving? Those vital "I'm driving a car" updates?

It seems to us that any activity which requires concentration and the use of both hands is probably not the best time to be Tweeting, but most of us are over 30, so perhaps it's a young person's thing.

At least it's easy to use: one just registers a mobile number and Twitter account with the service, which then uses CallerID to identify incoming messages and posts a suitable URL to be heard by one's followers. Assuming they don't kill themselves trying to click on the link while driving their car, of course. ®
