I assume that when a post has some odd spelling or word use, it's an-auto-correct glitch imposed by spell-check. No big deal. As a sentient being I can compensate and figure out meaning, which is the whole purpose of communication.
As for word choice, I am fine with "scrappy" and I don't think changing to another term is going to change public perceptions. But sometimes I like to describe my quilts as improvisational or serendipitous -- which really just means that I didn't plan ahead and I figure out how to make the scraps look kind of cool.
My observation is that quilters (and everyone) can gain huge power and happiness from being secure enough to make what they like, without need for external validation. No need for apologies or pointing out mistakes or quibbling over describing words. Make what you like, own it, and be happy whether or not anyone else comments or likes it.
