To the OP, no, the cliffhangers on the recruitment threads don't bother me in the slightest. Since a typical workday for me runs 10-11 hours, I figure that other people have demands on their time as well, and it may be a week or four before they can post. Or as TPARose said, maybe the posters just want to drum up a little excitement.
My only problem is that if they take their time posting the result, being of a certain age, I tend to forget the beginning of the story. So I have to go back and reread it, in order to recollect that a certain girl just *loved* "Rum Raisin," but couldn't stand "Cherry Garcia".
Yes, a few of the posters strike me as being somewhat needy of attention. But I work with at-risk children, and for some of them, when they need attention, they throw furniture, or hit you.
So as far as I'm concerned, these posters are just *fine*.
I also think that no matter how many neatly-set up threads a board may have, there will also be lots of excited newbies with the same old questions. Let whichever experienced boardmember who happens to be feeling fresh that day answer the question politely and direct the poster to appropriate thread(s). If it's not your day/week/month/year/decade to be feeling fresh, take a pass.

IMO.
