Meh, it must be nice to have faith. I have spent months trying to assume that there's a good reason for this, but I really don't think so. I don't know anything about the man's private life other than what I read here, but it sounds unlikely that anything truly awful would happen to him without someone in his online life being aware of it. If someone is aware of "it" and hasn't said something because Dom has asked him/her not to, well, that may be justifiable, but after a year, it doesn't really do much to temper my assertion that he doesn't care about his readers at large. Whatever has befallen him, it would be high time for him to ask Myr or someone to say "Can you let them know you don't anticipate anything more from me for the foreseeable future, and I'm sorry?"
I think it's more likely that his muse left him, he got tired and cynical as a result of bitching and carping from fans over email, he threw up his hands (consciously or unconsciously), and just neglected to tell the rest of the fanbase. I can understand that, but again: a year is a long time to go without saying: "um, guys? I'm not feeling it anymore. Sorry."
My judgment clearly doesn't matter for much in this case. Maybe, though, this will pass by the eyes of another gayauthor, who will at least reflect on the fact that some people prefer closure over lingering uncertainty in cases like this.
