Practice smiling in the mirror. Sounds silly, but it helps. I have found that facial expression is one of the main factors people use to initially judge whether to approach or avoid. Go to the mall or a club. Watch other "more social" people carefully. Watch how long they make eye contact when passing a person. Watch how they hold their body. Watch what their face says. Go home and practice making your face say that. Try to look happy. The best way to do that of course is to feel happy. Another thing I've found (some people might disagree and that's ok)... lots of programming time can sometimes lead to grumpy face or sort of crazy face and you have to work to offset this if you care about interaction.
