Social Bookmarking for Introverts

• Pinboard is a fast, no-nonsense bookmarking site for people who value privacy and speed.
• There are no ads and no third-party tracking. You pay a few bucks a year, and that's it.
• Pinboard lets you bookmark from any browser, connect up to three 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.
