>> the first instance of this conference, which they intend to run yearly.

Yeah but the F is FOSSY stands for First. Either they change the name next year or it doesn't make sense.

As someone mentioned Fossdem, the is also the LibreGraphics thing, and perhaps some other smaller ones.

The name is IMHO a very poor choice. My suspicion is they actually thought this would be a first of its kind, but that would mean they are not the right people to do this.
