A friend of mine told me about this one in class and after hearing about it? Oh man, this might be the coolest free service that I've heard of in a long time.
ChaCha is a text messaging service that if you have a question? You just ask them. Just text your question to 242242 and they'll send you a text message with the answer within the next few minutes (varies with the time of day). Believe me, I asked them about woodchucks chucking wood, airspeed of unladen swallows (african AND european), and George Carlin's certain family unfriendly words. And I got good answers back. Of course, I did ask some serious questions tonight too, but those are never the fun ones… You can also get weather and stocks from them too for wherever you happen to be.
The online aspect is cool as well. You register and tell them your cell phone and then online you can access your most recent questions if you happen to be away from your phone as well as ask questions from your computer too.
Needless to say, standard text messaging rates apply, but it makes a good time killer when you're running around on the go and need to know information… Or if you really needed to know things about swallows…
