Pingie

Pingie is a new web service I just read about which simply asks you to enter an email address, mobile phone number, and RSS feed URL.  When the feed updates with a new item, Pingie will send an SMS text message to your phone letting you know!  This is exactly the kind of web site I've been waiting for - there are many occasions when this would be handy; searching for something (like a Wii) on Craigslist is the obvious one which comes to mind.  Cool!
