Every time you create an account at a new site, you're opening up a way to get hacked. Because, like most humans, you probably reuse passwords, or at least have password similarities. And many web sites tend not to have the resources to properly secure their user database.

So, accounts on every new site you visit is both inconvenient and slowly degrades your security.

You could switch to centralized identity silos, logging in with Facebook or Google everywhere you go. Now you've got the problem that these big companies are tracking your every move, enforcing "real-name" policies forcing you to unify all of your web activity into one account, etc.

Persona is the best of both worlds: convenience and reduced security exposure, plus your choice of identity wherever you go with much better privacy.
