I am not an active member of FaceBook, MySpace, LinkedIn or any other social networking site. I do not play any MMORPGs. I do not have an active account on any message board, discussion board or any other conversational forum. I do not use Skype, AIM, ICQ or any other chat program. There may be some remnants of past activity in these areas, but I no longer check them.
I have this blog, an email account (that sufficiently clever readers of this blog can find), and a phone.
If you try to friend me, or buddy me, or whatever it is that's done at these sorts of places, I'm not ignoring you: I'm simply unable to respond. Either I don't have an account (as best I can tell, FaceBook does not require an invitee to have an account), or I've long forgotten the password and I'm disinclined to retrieve it.
I make no judgments: if you use these sorts of media, good for you. They don't work for me, however, so I don't use them.
