I just unfriended my remaining three Facebook friends. If you were one of them, please take no offense. Facebook friendship isn't friendship, and Facebook unfriending isn't the termination of a friendship. What prompted this was an email from Facebook about 82 friend requests. These are all being ignored, so if you're among the 82, also please take no offense. I want to have friends but not Facebook friends.
I don't use Facebook almost at all. I much prefer ordinary email for private stuff and blog discussion for public stuff. I need to keep a Facebook account, however, if only because there are a few businesses and other organizations that have no way of being electronically contacted except through Facebook.
