> I've used Delicious for 12 years, with 10,000+ bookmarks in it

I've used it for 7.5 years with 22k+ bookmarks.

I stopped using it last year because of the downtimes as well.

> I was frustrated that the Delicious export went away

Too much load on their servers.

Instead of transferring, I simply made a simple bookmarker with similar functionality (allows importing) that I could self-host.

See https://github.com/dyu/bookmarks/ if interested.
