I've been been a Pinboard fan for years. I paid $11 for lifetime access back in 2011, and "upgraded" to an annual plan with archival in 2021 (mostly because I wanted to support the continued development of Pinboard, and that the time Marciej mentioned new features that were supposedly coming). I love Maciej's work, writing[0], and general vibe. Pinboard acquiring del.icio.us[1] after Yahoo drove it into the ground is one of the most delicious (pardon the pun) acquisition stories in tech history I think. I also enjoyed his micro-incubator thing[2] (I think he was giving grants of $50 or something).
Unfortunately over the past several years it just feels like he's gotten burnt out on Pinboard and has stopped developing and is barely supporting it. I guess that's fine if everything works properly, but I don't really have a lot of confidence in the future of Pinboard anymore. I personally haven't had any actual problems with Pinboard yet, but have read several accounts by others who have and have found support poor to non-existent.
