Congratulations to Pinboard, a bookmarking service that has reached the age of 11 years. That's an eternity in the Internet world, but I'm not surprised, because it is a service that I not only love, but consider essential. I've only been a member for 10 years, and during that time I've stashed thousands of links, which are searchable, cached, and virtually at my fingertips. Additionally, I have an archive of every tweet I've made since joining Pinboard, which might come in handy in court one day. (I kid, I kid.) It's also remarkable that Pinboard remains a one-man, lovingly crafted artisanal software operation. If you're the type who bookmarks pages so you can refer to them later, you should definitely sign up.
