I switched to Pinboard few months ago when Delicious committed seppuku and made their site completely unusable. First, Delicious just shut down their site for something like a week, then they resurrected some ancient version of their site that looks & behaves like it's from 2007. Then they switched to an old domain (del.icio.us) and broke every bookmarklet and plugin that used their API. (I'm guessing they're planning on selling delicious.com domain name, which is worth a lot of money, so they made the switch.)

But the worst part is that you can't even save a link with all these changes they’ve made! I was getting errors 90% of the time (maybe even 98% but who's counting) so it was pointless to even try to save (I gave up after 4 days).

Whoever's managing Delicious is probably the most incompetent person in tech. Their communication with usersbase has been atrocious. They made only one or two blogposts and remained completely silent on social media (Twitter) during all these disastrous changes. People were unable to get their links and the company remained mum. Number of "F Delicious" posts on Twitter was very high few months back. Their site still doesn't work and you can't save links (just tried).

Anyway, I found Pinboard and have been happy since. RIP Delicious.
