Me! I want to. I too want to practice talking on the phone - I tried it a few months ago with my friends after realizing that my speaking skills have been affected after being invalidated by someone i liked.
I like my friends, and what not, but they are the types who prefers to chat on aim, so it didn't work too well. They aren't very social in real life, so I have to respect that, though I don't like online chat since not only it doesn't increase social skills, it is hard to read the other person, which could cause a lot of miscommunication. Hit me up if you want to practice
