Will you regret your online presence?

Bloggers, Facebookers, Tweeters and more seem to be constantly besieged by warnings from young and old alike that we will regret our words, photos and thoughts. One blogger reveals, “I look back at some of my own posts and shake my head.” Online tools make it possible to change in front of the eyes of the entire world… And some believe this is going to be pretty embarrassing in the years ahead.

What do you think? Do you share enough to worry? How do you think your online activities will affect the future?
