When you first sign up and start adding services, it's very easy to accidentally click on the "facebook" link instead of the "+add" link. this takes you to facebook. wouldn't be a big deal, except when you come back you've lost all of the work you've done to add services to the right hand pane, or so it appears (it's empty). so i add them all again, being careful not to make that mistake. when i hit "ok, i'm done", it turns out that many of the services are there twice (so it did remember them, the UI just didn't agree with it).
