Johnanna Draper Carlson asks "When did Girlamatic die?" -- and creator Tara Tallan replies "Girlamatic isn’t quite dead… there are several comics that still update (mostly) weekly, such as Gypsy!, Faery Underground, Five Star, and also mine, Galaxion."
It does seem fairly clear though that Joey Manley (aka ComicSpace Inc) has largely given up on the original webcomics anthology model, even though four such sites remain in various stages of operation: Modern Tales, girlamatic.com, Graphic Smash and serializer.net.
