I think my co-workers are right as well - there probably is something better out there.

With the Twitter and Tumblr accounts, no family or co-workers are aware of them - any "housecleaning" would be if it's really necessary. (Besides I have a separate Tumblr to let my slashy fangirl loose - I just haven't really set it up.)

The only thing they know of is Facebook, and that's fine.
