I'm not sure how sarcastic you meant to be. I understand that everything like this has a redeemable purpose and place, but I think a vast majority of people have the wrong intentions. Don't get me wrong I like calling my grandma every few weeks and making sure her dementia has creeped up on her too much.
I hate when I'm writing a paper and a freind starts IMing me because he was bored. He dosn't actually want to do anything, there is a good TV show on, he's just seeing what's up. I think over-communication is to blame for some people's weak communication skills. It also enforces poor relationship building. Everybody becomes pretty faceless ("face"book, is that irony?) when the are all your freinds for no reason. One of my best freinds dosn't have a phone or a computer, and I feel most connected to him. We had to actually foster a relationship. A concept mostly lost on todays college campuses.
But I could just be bitter or full of crap.
