I don't know if a lot of people already know about this, but I just noticed this on Google today. Apparently, Google offers a free service where you can send a text message to GOOGL (46645) and they'll answer your questions. The functionality is limited, but it's very cool!

See http://www.google.com/sms/ for details.

Basically, I tested it out & typed in "FROM DCA TO (my home address)" and sent it - and it gave me turn by turn direction (in the form of 4 received text messages) to get from DCA to my house in Falls Church, VA - so this could be great if you're traveling & don't know where you're going & need quick directions. I also tried typing in "THE WEDDING CRASHERS 22042" - and it gave me a listing of all the times & theaters that The Wedding Crashers is playing at near the 22042 zip code - it's great!

And it's free! Note that this probably only works in the US & you have to pay for the outgoing text messages (I have an old AT&T now Cingular plan where I get 200 outgoing text messages a month & free incoming, so I'm not too concerned about the overall costs).

Check it out!
