I'm a little sketchy, so I could be saying something stupid, but, what's wrong with having a lot of private accounts? I think I have around 7 email accounts from various providers and websites, sometimes more than 1 on those site (I have 4 on google alone).
It's for my own reasons, but one reason I can say, with full lazy-pride, is so I don't have to switch between accounts per computer. Just assign an email to the computer which automatically uses it with password saver.
