I should preface this by saying that I'm pretty late on the whole texting curve, so this might be relatively common knowledge, but so far nobody I've mentioned it to has every heard of it and they all thought it was cool. Did you know that you can text Google on your cell phone? My brother was using it to get basketball scores the other day when we were at a Round Rock Express game. Basically, you just text "46645" (which spells Google) and then whatever you want to know about. Anyway, it turns out there's also something called ChaCha ("242242") that's similiar, but it actually sends your question to a person. (who presumably just Googles the question for you or something) It's kind of funny cause you can literally ask them anything. Anyway... I just thought this was cool. I had to sign up for unlimited texting cause it's too addictive.
I already knew about Google (Try 1800-Goog-411 for free 411 by the way) but talking to a live person is great with ChaCha.
