AskHN: Is Pinboard.in a dead project?

While pinboard is still up. It seems to be unsupported. There are people writing on twitter and they get no response. Emails are being sent to support but nobody ever answers. These are issues brought up in the pinboard freenode channel on irc all the time. Users have issues but can't reach support.

Does anybody have an idea on what's going on? This has been over the last 12 months.
