Correct punctuation has nothing to do with social interaction.
Millions of teenagers have had bad punctuation for decades. The only difference is that a bigger percentage of teenagers worldwide are being educated and going to college right now than they were say 20 years ago.
I am yet to see any scientific study that says teenagers don't socialize today, because they spend all their free time on social networks. Teenagers play sports, go to dances, go to night clubs, hang out the same as they did in my time. They merely use the internet to vastly enhance their social interactions.

It has EVERYTHING to do with the internet age. When I get a card with a note inside from someone that I met online, and the note says "prolly" instead of probably, you think that's not a problem?! Internet speak in taking over in kids communication outside of the internet. You can pretend it isn't a problem but us older folk see very clearly that it is.

We have a bunch of fat, lazy kids that sit their butts in front of a PC all day and you don't see a problem?

OK, then click HERE. This book (by a professor of English, no less) explains using decades of scientific studies (he used to be the head of research for the National Endowment for the Arts) how electronic communications are dumbing-down the young generation, substituting for real interaction and reducing the intellectual faculties of modern youth. They are faux-socializing... not really socializing (especially in ways that lead to cultural knowledge).

Now you can't say you've never seen scientific studies to the contrary...
