I have each one set up with the tags pinned as needed - so for example with multiple Hive accounts I have each one ready with peakd, hiveblog, hivestats, hiveblocks, and hivevote all logged in and ready to go on each different account
and i have a bunch of other sites where i'm doing the same - so my browser is my persona - frot is firefox (with purple add on) - the browser tells me who i am!
