I found a number of my steam friends via the facebook integration. It's an easy process, you go to a page in steam, it shows you who on facebook isn't yet in your friends list, and then you check boxes to add them to your steam friends.
This is all well and good, but because the namespaces are completely different, there's no way to know what friend ladayada71272 on steam would be on Facebook. And I absolutely cannot find a way to get that information.
Normally I wouldn't care, but someone gifted me a game and used my name, so they're obviously someone I know on Facebook but I have no way to thank them and know who they are in the process.
Is the Steam interface broken or is it me?
