I posted the first chapter of a new story today, and I added a request in the end note (which I normally don't bother with) to PLEASE not rate it based on that first chapter. Whatever, five readers rated it anyway, but two were 10's and one was a 9, so I guess I shouldn't complain.
I don't know how well it fits this situation, but as I said in my stories (and Murphy has said), "If it's stupid, but it works, it's not stupid..."
I would say, rather, "If it's stupid, but it works, then that's what the audience wants... but don't assume they'll always want it." You can only get away with stupid for so long.
It's also possible that you're being upfront at it, they were congratulating you on your honesty about the first chapter, and then are waiting to post any later updated scores.
As the saying goes, "You can cure ignorance, but there's no cure for stupidity!"
Not even duct tape can fix stupid, but enough duct tape will make is shut up for a while. :)
