I'm with JoAnn, respect anyone who wants to use those things, but not for me! My cell phone is primarily my "car" phone, I don't text or do anything else on it but make phone calls out of the house. No way am I interested in sending out daily messages about my daily activities on FB. I must have inadvertently signed up once for Twitter, and then started getting messages "so and so is following you on Twitter", and quickly got out of that one. Great for biz, I guess, but I have no need to promote one because I don't have one! And get more information than I need without all these distractions!
I'm just one of those old dogs who has already learned enough tricks to keep me more than happy.
