For most of us, when we want to easily share files, we use apps like Dropbox or Box.net. But what about the rest of the world? Admittedly, even Dropbox is a bit too complex for some users. You know the type, right?

filefly is a new app, built on top of Facebook, which allows users to drag and drop share between themselves and other Facebook friends. Where it really succeeds is not only in having immediate access to your entire Facebook network, but also in its brain-dead simplicity.

If Dropbox is just too difficult, or if you want easier access to your Facebook contacts for file sharing, then filefly is a must-know for your apps arsenal.
