Unfortunatly, I am caught in a dilemma there. See, my nature is to tell the person why I am unsubscribing, but I also do not want to give unsolicited critiques, as that can be harmful. By that token, you have pointed out that unsubbing without telling them why can have the same effect, therefor I have resolved to only do subscriptions on Comic Rocket where people can't tell who I have unsubbed. I will be informing everyone I am subbed to on this and several other services that I am switching all my subs to Comic Rocket, and that will be the end of that.
I'm finding my audience. I write for me, but in writing what I want to read, I know I am also writing what others want to read. As I mentioned earlier in the thread, I want fans. I want people who like the story enough to keep coming back, and to get invested in the characters, and the world, and when the second NO-Earth title starts up in a couple of months, to be ready for that. The subs are one gauge, but I don't put a lot of stock in them. I have pageviews, likes, subs, session counts, pages per session, comments, and so on. Over half my hits on my main site have no referrers, which means they either typed the site name in, or had it bookmarked. There is a list of things that I use to gauge how people are liking the series and the site, even those that never sub, comment, or like.
My advice is stop placing so much importance on subscribers. I can't remember ever having judged a comic on the number of subscribers. I am on another forum where some of them judge the comic based on the updates to subscribers ratio. If the two numbers are close, they figure it's a good comic. Sillyness. The best way to judge a good or bad comic is to read it (or attempt to).
And by the way, I only have 7 subscribers over here. And I only have 1 comment every other update. I think I qualify as an underdog here.
