Had to add that your fandom name isn't mrssnape or sevvilvr, either.

My 2 cents

I keep my online life seperated from my professional, work life, mainly because I don't want coworkers I see everyday to know of my fannish tendencies.

That said, if being well known in fandom were to ever help me in RL, I'd be all over opening up the connection (after taking a little while to filter away a few things).

Then, if (this is purely hypothetical for me, quite possible for you) I suddenly became famous, I'd probably create a new online name to hide from people and just have fun.
