how far is too far?

I have a question. A deep, burning, need the answer now kind of question.

Is it ok to add someone whose blog you faithfully stalk to a social networking site(Facebook, MySpace, Twitter, etc)? It's one thing if they don't give you any of their information (like their real name, real location, etc). However, what if they make a point of giving that out and make it clear that you can add them? I just can't decide.

On a side note, I think I overuse parenthesis. Maybe because a lot of my thoughts involve layers and parenthetical side notes? Sure.
