There is one reality all of us are familiar with: multiple accounts. It’s hard to find somebody who is at least a semi-regular on the web surfer who doesn’t maintain multiple accounts. For example, an person may have:
- several email accounts - perhaps one Yahoo account plus two Gmail accounts (one personal and one "family" account that is shared with family members)
- a Twitter account for personal and business interests
- a Facebook account for keeping up with their social graph.
- a PayPal account for online commerce
- a Windows Live Messenger account for chat
- etc.
