Since Delicious collapsed on itself, I’ve been happily using Pinboard to save my bookmarks online.
Like most social bookmarking services, Pinboard has a popular bookmarks page. Unlike many others, the links are often very good and the page does a good job compiling the articles that a lot of people are talking about recently.
Aside from a few tags to go with the links, you don’t get a lot of context or information, so think of it like a very excellent “Random link” button for the internet. Worth checking in on every now and then.
Comments? I don’t do open comments. Life is too short.
