Petra Well, as I said (someplace above), people might not tell me something negative or I might simply miss out on some very fine folks who didn't reach out at all—but all the things that have been mentioned about my proposals have been high praise... in fact, kinda higher praise than I expect, but I have been making proposals to clients for a very long time so maybe I really do write "the best" proposals that (some) people have seen (in my field) on UW?? I can't really fact-check that, haha...
But yeah, as also mentioned someplace above, it's advice written into Upwork's own onboarding & FAQs (unless they've updated it)—so between UW's recommending it and it seeming in my mind (and from occasional direct feedback) to be a good way to do things, I've just continued on with it.
It appears, from this very interesting discussion, that it's time to see what happens to my stats if I do the pre-click intro differently.
