I've been on the great festering garbage scow that is Drunk Duck not once, but twice (shame on me) and the first time I left there to host exclusively on Smack Jeeves, PoY had a bigger audience on DD than on SJ. I did the same thing, left a message explaining why I was leaving DD, put up a link to the SJ site and even posted a couple more pages to make sure all my readers got the message. With me it was the same, some came, some didn't. I was concerned for a long time that so many readers didn't follow me to the other site where I was still updating, but the more I came to a realization, and I hope you'll all pardon me when I say that the realization was "Fuck those people."
Honestly, while it's a nice idea to want to retain as many readers as possible, it's not possible. You're better off spending the time and energy you would spend chasing those old readers instead finding new readers. Drunk Duck is a horrible site and even the community there seems to be crumbling. If some or even many deluded readers can't wrap their heads around the idea of visiting a comic off that broken-ass site, the answer is not to split your attention. Let them go and let them rot. Maybe they'll come find you when DD finally disintegrates into a pile of rusted servers.
I don't understand why anyone is still hosting their comic on that bucket of old tampons they call a website.
