I'm on the edge of a milestone too, almost at 10 subs Not quite as big as yours but, hey, it's early days still!
The one by someone else I want to promote is Flaw, a webcomic that has a wonderfully rich world and characters that you can really relate to.
This is mine, a fantasy novel that I hope hits the same points I made about Flaw, but that's not for me to decide, eh?
