I have just decided to leave Facebook.
The reason is this -- all I am using Facebook for is a place to link my blog posts via Twitter integration. I have hundreds of friends there (about 30% of who I actually know), and do not have time to do anything else on it. It seems unfair to me to have others try to interact with me there when, in actuality, I am not present on it.
So a poke to everyone who has been poking me!
If I start seeing a big drop in blog hits, I might rejoin it. It will be an interesting experiment.
