Well Hello fellow grammer scolds!
Here's a website you might enjoy:
http://www.apostropheabuse.com/It's only going to get worse folks. With the rocketing popularity of Twitter, poorly punctuated and incomplete sentences will become the norm for much of the population. On the positive side though, anyone with marginally above average writing skills may have a bright future.
But more seriously, I think this is an another example of the bifurcation of our society. We are headed towards two classes: the educated who will do well, and a large underclass that will barely eke out a living. A lot of kids will grow up thinking text speak is acceptable without realizing it's a silent handicap.
Much like dropping "He aint got no..." into your conversation, which immediately bestows upon you (rightly or wrongly) much about your class and education, text speak will do the same for your writing. I would be amazed if kids weren't already using it on their resumes.
Another example - table manners. And I don't mean confusing the salad fork with the dessert fork, or even talking with you mouth stuffed full. I've seen beautiful, well dressed, college educated young women (yes even some relatives) eat like pigs at a trough. Yeah, guys too but it seems more shocking from the women. I've been to enough business lunches to know that the people that eat like this are not looked upon favorably, and hurt their advancement.
But back to the topic. I think all you can do is push back (against text speak) in you own life. Don't respond or ask senders to email you when they can write out their message. I've done this with regards to cell phones. When someone calls with a lousy connection or crappy phone and I know it can wait, I insist they call from a landline or better cell. Life-minutes are too valuable to keep repeating "What?, What?, What?" Same goes for deciphering text garbage.
