.. so many threads just seem to tail off into nothing ..
.... They take the trouble to post here,
but often seem to give up very easily ..

I'll second those perceptions. And it appears there's also so many "one hit"
threads around that responders never really know whether their responses did
get through to the OPs. An amazing lack of closure ..
