It was a hard decision, as I had a lot of fun working on it and it was a fruit of passion, but the decision was taken long time ago (October-November) and the final graphic was implemented back on February: the writing was on the wall for quite some time. I continued it for months mainly due to my stubborness and waited for a milestone and a credible(?) excuse to get out.
Good thing I didn't set any performance metric for the comic, otherwise I would have been sad about it not meeting any of the expectations... So not having enough data, I can't make any conclusion: it failed due my poor implementation (graphics, stories) or due to my decision to address such a narrow niche (Fedora and Fedora on the desktop). But I have enough data (comments, traffic, link backs, translations) to conclude it was a failure.
