I feel like I am missing something. You were fine with service and value that it provided until you found out that Maciej is not busy enough running it?

Why would you care if you get more value than you pay. Or alternatively, why would you pay for it if it didn't?

Are you switching only because of the above reason or is there something missing that you'd like to find elsewhere?

I am, too, a long term Pinboard customer. I don't care if Maciej does no work whatsoever in an average year as long as Pinboard works or is fixed quickly when it doesn't. I may be biased, because my wife and I both enjoy his writing and talks a lot so it "feels" like we are to an extent sponsoring that too.
