Over the years, Facebook has slowly morphed from a voyeur's wet dream into what is now essentially a popularity-based RSS feed. And since there's only so many listicles one can read in a day, Facebook just added a "Save" feature that compiles all your readables for viewing at your leisure.
Just click the little arrow on the corner of something that piques your interest, hit save, and the item will be added into its own (private) section. And if you have a tendency to forget about things you've saved for later, Facebook will occasionally send you a reminder in your News Feed, which, as far as Facebook goes, is relatively unintrusive and handy.
If the whole concept feels remarkably similar to Pocket or Instapaper or Readability or any of the other dozens of apps that saves content for later, it's because it is. The difference here, though, is that you'll also be able to save topics your friends are chatting about (shows, music, etc.) for you to check out later.
There is one major drawback, though—you can't access any of your "Saves" offline. Which kind of seems to defeat the whole purpose. Of course, Facebook is constantly evolving and experimenting, so there's still time for them to change that yet. [Facebook]
