I have 5 with Metrocast (the most they allow)
1 for family and friends
1 for shopping ( so when they insist on an e-mail address, I restrict the "crap" to that one account)
1 for work accounts
2 for forum type sites I'm on a lot of photography and wildlife (not that kind of wildlife! the animal kind of wildlife.. humm.. when you're in a hole... stop digging!

))
