There's a story behind it - apparently there was a better response from consumers with annual pricing. People often didn't understand the concept of a one-off fee for a web service, and got confused between the once-off and the recurring options

> Right now, users pay a one-time signup fee that grows by a fraction of a penny with each new signup. At the moment, this fee is $10.55. Pinboard also offers archiving accounts, which cost $25/year. Users who upgrade after joining Pinboard can deduct the signup fee from the first year of archiving.

> Under the new scheme, basic Pinboard accounts will cost $11/year, while archiving will continue to cost $25/year.

> My main reason for making the change is so that I don't have to keep explaining how pricing works. An astonishing number of people already believe that they're paying annually for Pinboard. Others accuse me of baiting and switching them when they upgrade to archiving and get a renewal notice. Note how much easier it is to describe the new policy than the old one.

So he changed it from a one-time cost of ~$11, to a recurring annual cost of $11? That seems like a pretty big change.
