I was referring to the claim that the root word of twitter is twit, as in an idiot. Perhaps it was just a pun, but it is making a connection that just isn't there.
The problem isn't that this generation is dumber than previous generations. What you are seeing that this generation actually does communicate more. The downside to that is that just as has always been the case, most people are dumb. You just didn't notice before because they had no way to tell you. It's like violence against kids. We live in an age where it is at an all time low, yet most people think it is more than ever because they now hear about every incident in the country, where as a generation ago, they only heard about it if it was in there state. A generation before that, they were luck if they heard about it when it was just one town over.
You really shouldn't complain about wasted bandwidth. Just as I told my father a decade ago when he would complain about people using the internet for voice chat... It is the bandwidth 'hogs' that push the envelope. They set the bar, and the rest follow. For half a decade now, my phone has been run over the internet, and no one thinks twice about it. Because of the bandwidth 'hogs' of last decade, I can now stream movies in HD to my TV from a selection of thousands of titles. The bandwidth 'hogs' are our friends. Bandwidth usage is graded on the curve. Someone will be setting the curve for the class.
I am not a fan of facebook, or twitter, but I can definitely say that the internet has increased my letter writing by at least a couple of thousand fold. Prior to the internet, I wrote at most 2 letters a year. At most. Today, I write half a dozen a day at least. This being one of them. Letter writing isn't dead. It is just delivered online, and it has exploded in popularity. The phone? That might be used a little less, but that is only because people do so much more of the communication in notes.
I will agree with the atrocious spelling and grammar though. I am not a stickler about either. I generally go with the fact that complaints about spelling and grammar are more frequently not, internet speak for "I don't want to agree with you, but I have nothing to refute what you say, so I will look for spelling errors." I avoid complaints about spelling and grammar because we all make mistakes now and then. Declaring someone wrong due to poor spelling can only lead to a declaration that you are wrong yourself. That doesn't mean that some of the stuff posted doesn't look like it was written by a retarded monkey.
