Pinterest update

Pinterest is expanding. You can now register as a business, which gives you additional options, and it's still free.

There are two ways of setting up a business account: you can convert your existing account (useful if it's already established and about your business), or start a new one from scratch. There are new terms and conditions to sign, and, at the time of writing, you have to follow five other pinners to get started.

At present there appear to be no plans to charge, but Pinterest is going to have to start earning at some point.
