"Tweet your Google Calendar " is the tagline that Twittercal has at the top of their website. As the range of Twitter applications grows it seems logical that more and more productivity ideas and ways to use Twitter in this regard will come to light.

Twittercal is a twitter bot that allows you to send a special coded message via twitter, through any twitter channel (web, sms, mobile, twitter client etc.) that will update your calendar at Google.

While it is a good idea in theory, I would have thought that most business people have a blackberry or other smartphone that does calendar already. Then again, maybe this isn't only for business people!!
