Quicksilver + Social Bookmarks plug-in + delicious is my favorite web browsing tool. Pinboard.in is a new bookmarking service that's attracting many long time Delicious users including myself. I hope someone adds Pinboard support to Quicksilver.
>From their website: Pinboard offers a full API, modeled on v1 of the del.icio.us API, which you can find documented on their website. Simply replace the endpoint in the examples with https://api.pinboard.in/.
