Actually.... early this year, an individual decided to recreate Avid Gamers on avid-gamers.com , however, after only a few months of attention, in rolled trolls, haters, and drama. It should be no surprise that a service for all-ages attracts immature folk. The creator of this rendition had enough and threw in the towel, shutting down the site. A different site, ageans.tatelu.com sprouted up, which seems to be a hang-out community for its former denziens.
Goodpixie.net claims to be working on its own reincranation.
Given the pattern, I have no doubt there will be more projects in the future. But given the work involved in programming (you know what I mean), there is no telling whether or not any of these projects will actually succeed, release, and open - or even live very long after that.
As for where these folks are now, some no longer care about literate roleplaying / collaborative writing, while some do. Roleplay directories and resource sites sprout up here and there and are frequented by roleplay folks seeking services and comradery. Your biggest chance at finding old friends are to scout the resource sites for old AGers. RPG-D is the biggest, longest standing, and most active of all of the directories, so it might be a good place to start.
