The stackexchange unified system works pretty well. You can check all site activity through one simple interface, and everything is neatly tied together.
Which is great.
Except when your "hobby" sites (parenting.stackexchange.com, gaming.stackexchange.com, one of the religion.se.com sites, skeptics.se, whatever it is) may reveal too much about you. Employers can conceivably use personal information to bias their hiring. This is Not Good™.
I'll post a solution I have for this below.
