Let me stress first of all that FSDN was a ploy on the OSDN name. Nothing more than that. It was never a serious attempt by me to create a network like OSDN; I could never do that, at least not alone.
But it has become clear to me, from comments here and from the emails I've received that people do want it to evolve into something more serious, so I've created a mailing list where such plans can be discussed. My thoughts can be found in the archive of the FSDN mailing list, which is here. Information on subscription is here. So if you want to see FSDN become something serious, this is the mailing list to join.
Now for the change; as of right now, FSDN is nothing more than a list of websites which are dedicated to Free Software in one way or another. You can submit ideas of sites to me and if I think they are valid candidates, I'll add them to the list. The list is used to create the FSDN banner on top of GNU-Friends, and you may snarf the network list to your own website if you wish, but noone has to do this, and I don't know exactly why anyone would want to, but it's there for those who still want to :-)
