It happened. Delicious closed its doors for me too. I'm not longer able to add and save bookmarks on Delicious. You're still able to scroll through the pages and use the bookmarks already there, but no new ones will be added (if you wanna know what happened, look at this announcement). Thankfully I always crosspost all bookmarks on Pinboard (AND save every single story on my harddrive).
So from now on, I'm only going to save the stories I'll read on my Pinboard. AND I'M AT 4.759 STORIES OVER THERE. Lets see if I'll reach 5.000 this year.
I also had a Delicious for Audiobooks. But I'm not sure yet if I'm gonna open another Pinboard account for them. Maybe I'm just gonna add them to my regular Pinboard with the appropriate tags.
