I have to look at the keys to type, but I am not so slow. Typing on the touch screen ended up been a lot easier for me than I thought it would be.
I tend to write posts right when I think of it, so hence, using the phone. I don't have a tablet, I don't see the need for it. And I do post almost every ride, since I don't post it anywhere else; occasionally I write something on FB about a ride, but my non-riding friends always ask, "Don't you ever stop?"
My sons are a little old fashioned for their age in terms of tech use. The only annoying habit they have is the older one *never* listens to phone voice mails, at least from me or other people he knows. He does call back, but sometimes I get annoyed when he asks, "What was that about?" The older is not on FB, after being a prolific early user. He thinks Twitter is stupid, but he has had a blog since college (not sure if he still does). The younger one is on FB, but never posts and also thinks Twitter is dumb. He is better about the phone stuff. They both respond to email, though, even though we text if we need to get in touch quickly. I think that the older needs to use email a lot for work, so it's a habit.
