You seem to have been an early beta user, Lon. At least I noticed that some of your great headlines correspond to older pieces. I think back then Medium was still employing an army of interns (a.k.a. curators) and these just didn't know what the heck they were doing. So instead of promoting your obviously brilliant articles, they interfered.
But I think they've been fired, so you should be fine now.
In any case, you seem to be one of the few writers who gets headlines right. I mean, that alliteration one is pure genius. So maybe you don't need the autocompletion feature...
