I have to 2nd the sentiments of Ben and the OP. I don't use FB but that may be a nice middle ground. It may not result in more traffic but it makes sharing much easier. There are many times that a fine article on here recommends a good practice or way of accomplishing a task. I attempt to share it with co-workers or colleagues only to but up against the registration issue. Then I have to go digging to find another article that makes the same recommendation. I should be able to email or IM a link to someone and be done with it.
