I found I liked a fair amount of your stories myself. And yes you haven't seemed to have posted in awhile but that is entirely up to you if you wish to do so or not.

the retcon universe is, quite simply, fun to read. There is quite a few different characters not yet written about that can be added.

Keep up the good work

...at least part of the reason for people's grumbles was due to your creative process: it appeared as though you'd work on a story and post chapters until you hit an impasse ("Where the heck do I go from here?! I had ideas a month ago but they've now evaporated. B*gg*r."), then start work on another, returning to the former at a later date, several stories down the line. I can understand both points of view (you like to post new chapters as soon as they've been written, fans like to see a regular posting schedule), but as you say, you may get better fan reactions if you wait until you've completed a story (or two), then start publishing it (them) on a regular schedule.

Maybe at some indeterminate date in future, The Center or Comics Retcon universes may be revived - or you're bonkers enough to write more tales for the DarkRealms Universe :D

Perhaps in the meantime, post occasional non-specific update blogs along the lines of "I'm currently actively writing 3 stories - one's about half way through, one's nearing completion, one's just started." That way, you've giving fans some idea of what you're up to without revealing exactly what you're working on (or whether the story that's half way complete in update 1 is the same as the story that's nearly complete in update 2!).

Or maybe, just maybe, create a new universe with a scene-setting story, then move to more of a curator role than a writer role...
