bebo is only used as it is full of slags who post revealing pictures of themselves
myspace is shit, and i have logged in maybe once in 2008
facebook is the one i use most, especially with the twenty20 cricket application
I have Facebook only. I looked at Myspace once about a year ago and thought it looked a bit messy and was mainly full of teens. I've never seen or used Bebo before. I'm happy to stick with Facebook for now until that fad is eventually over (just like ICQ, Napster, etc).
Facebook - for all the reasons Mrs Coach so eloquently provided.
But being an miserable old git I routinely KILL the more irritating Facebook applications. Oh, and I have been known to excommunicate people who can't get their heads around the simple "skip this" option and instead, invite every single sodding person to sign up for sheep throwing or wotever...
