Text Messaging is now a sport! A really addictive hobby for teens and for bored grandparents. It surely gets the short and curt (or even sweet message) to the receiver. Most mobile phones nowadays have adapted its interface to other texting options opened up by the web like twitter!
If you're not really into texting or the the short message phenomenon, maybe its time you stop living under a rock and get in sync with this new form of communication. It won't hurt to try it for awhile! In fact, you might come to enjoy it!
On my end, maybe its time to rest my sore fingers:)
