I don't use twitter or facebook either, but do understand, it is the thing of the present.
Just because we're behind the times doesn't mean we can't learn, and if we want to remain a dinosaur in todays high tech environment, it doesn't mean others should have to give us special treatment and baby and pamper us. It's our choice.
This is no different than those who constantly expose, "Read the TM's".
Life is about what you learn along the way.
Maybe I'll learn twitter. Facebook is an outlet of privacy information that should never be let out. Beware, it can, and will be used against you, if need be.
Off my soapbox....
