Pinboard

Founded in 2009, Pinboard is a fast, independently run, no-nonsense bookmarking site for people who value privacy and speed. There are no ads and no trackers of any kind. Users pay a modest yearly fee. Pinboard lets you bookmark from any browser, connect up Twitter accounts (and favorites), and sync with popular services like Instapaper or Pocket. For a few more bucks a year, Pinboard offers an archiving service which saves a copy of everything you bookmark, gives you full-text search, and automatically checks your account for dead links.
