Why would an Original Poster not acknowledge responses?
Two weeks ago I responded to a Kitchen Forum post that was off-topic, and (with my dearth of knowledge about kitchens) it was the rare occasion when, with a google search, I could offer an answer. The OP's question was time-sensitive, and perhaps that's why mine was the only response. In any case I never found out if I'd given her what she was looking for.
I don't expect effusive expressions of gratitude, though I do often see them--and even offer them! A simple "ok, thanks" would do. Her non-response stood out because I rarely encounter it on this, the most congenial of forums.
Curious if she 1) was frantically busy or 2) had dropped dead after posting, I just did a search. Nine of her threads elicited responses, and in all but one she disappeared after her initial request.
Fortunately, most folks seem to recognize that we're a community of volunteers and that busyness doesn't outrank courtesy.
Anyone else experience this lately?
