Slanguagely: "There is a hitch in your get-along", implying "there is a difficulty with your system/process/activity"

That's not what that means! If you want to put a hitch in my gitalong, for example, you might try a really saucy compliment.

I won't argue that the usage can change, and I could see how it could also be used to imply that one's posterior moves in a pleasing manner, but in my experience it has only been used to indicate an issue:

Marjorie Kimmerle & Patricia Gibby, "A Word-List from Colorado," in Publication of the American Dialect Society (April 1949) has this entry for the term hitch:

    hitch: n. A crick ; a limp. Used only in the expression "He's got a hitch in his git-along." Said of horses and people. OED, A limp, a hobble, an interference in a horse's pace.

Which experience would this be? That is a Stack Overflow link you posted. But I would expect such a footless prescriptivist to behave in just so ill informed a manner; excuse my short patience, I understand this actually is your best that you're showing.
