I really hate that old tale about the man telling the doctor "It hurts when I do this!" and the doctor advising him "Don't do that." But here I go (with apologies):
Why are you trying to convince people to get on twitter? Twitter scratches an itch. An itch I have. An itch it would seem you have. But not an itch shared by everyone on the planet. If you had a friend who was complaining "Gosh, I wish I could loosen this bolt without making my fingers all bloody," it would be appropriate to introduce him to wrenches. That doesn't mean you should be hounding him to use it to eat his cereal in the morning or brush his teeth at night.
If a person has a need for twitter, explain how twitter services that need. If he doesn't, well, he shouldn't be on twitter and no argument from you will change that.
