I have killed my imaginary pet by deleting my link from Facebook to the only game I kept playing.   For a long time, the only reason I would log into Facebook daily was to feed the guy and make sure he was happy.  Every time I took a weekend off and had to look at his pitiful poor starving posture and filth I wanted the freedom but couldn’t make myself do it.  Now I go days without thinking about logging in and it’s wonderful.  I think it’s just one of those things that you make yourself need when you don’t.  You know those things, like all web 2.0.  I’m not going to make any great argument for or against living part of your life online.  I certainly am not one to talk either way.  But if you should want to leave the net there are a couple of options out there:   web 2.0 suicide machine and vanish:  self destructing digital data.
