If you belong to social media sites such as MySpace, Facebook, LinkedIn Twitter, Flickr, et al, you probably face this question each day: Should I add this person as a friend? Most services will send you an email alert that someone has requested that you become their friend. Now it’s up to you to decide to accept or ignore it. On Twitter, you can become a “follower” for anyone and anyone can follow you — but who should you follow? On Facebook, friends can see your entire profile and pictures. So who should you let in? People you know? You’ve met? Work colleagues? School buddies? Where do you draw the line for online “friends” or do you refuse to draw the line and just accept anyone who asks? Share your strategies in the comments below and I’ll post the best ones in the next Your Take Roundup.
