One of the weird side effects of the Facebook era is the people you haven't talked to in ten years who post "Happy Birthday!" on your wall once a year. If you want to look that thoughtful . . . even though you're not . . . we finally have a solution for you.

A web developer just released an app for the Google Chrome web browser. If you're not using that browser you can download it . . . and the app . . . for free.

The app checks which of your Facebook friends is having a birthday . . . and then automatically posts a "Happy Birthday" message on their wall. You can even choose to have it rotate between a few different messages.

Now you can wish all of your long-lost friends from elementary school a happy birthday without actually having to do ANYTHING.
