It reminds me of some years ago when I used to hear some folks not trust having an email account, for risk of being spied on and now it is just replacing the physical mail. Certainly it is important to keep in mind the long term presence of these means of communications. It is like making sure that one will want to raise kids with someone before having sex with them, there may ensue a really long term situation. Still, even the die hard resistant ones when they come to see the need, fall for these conveniences. And, thanks to social media one tweeting buffoon gets to be on top of the world. Could do you greatest benefits but all the same could cause one's undoing.
