Ask HN: What happened to Pinboard?

Over the last year or so, pinboard.in's paid archiving service has become increasingly sporadic. The process used to be nearly instant, but bookmarks are crawled maybe once a month now and frequently fail to archive correctly or are skipped completely.

From Pinboard's Twitter mentions, I can see I'm not the only one who has been trying to contact Maciej for several months without success. A lot of former delicious users are also desperate to get an export of their data, which is still unavailable over a year and a half after Pinboard purchased and shut down the site.

Overall, it's left a pretty bad taste in my mouth. I decided in September to leave the service, but emailing is the only way to request a full download of archived bookmarks. I'd also like to get a refund on the next four years of my archival subscription - I paid for five years in advance because I was so happy with the site before now.

I know Maciej reads HN, and there seem to be a number of Pinboard users here (it's still mentioned just about anytime somebody posts about bookmarking). Has anybody else had any luck getting a refund and a copy of their data? What are the best Pinboard replacements, self-hosted or otherwise?
