The best way to deal with THIS particular scenario is to look at it from POSTER’s perspective. (when I say POSTER, I mean some1 having some problem and looking for advice) so where he/she should start from? Health & Fitness or Life1? lets suppose he/she couldn’t find anything in ALREADY posted threads. Next thing to do would be opening a thread and ask for advice. OK now don’t be naive we all know that how it goes in life1 threads; remember those hymenoplasty and facial hair growth threads? I admit that I myself was so close to upload a Gillette Mach3 image 
; anyway the point is that within hours members start replying with home remedies and what else; EVEN if a PROFESSIONAL response is posted, it is lost in sheer number of sympathetic/fun posts. 
now lets suppose Tasha opens a thread for assistance covering one SPECIFIC topic, which has no interest for common members. The chances, that Any1 who has experience/knowledge of that topic will pick that thread, are very slim. for the reasons:
A:- there will be none or very few replies in the thread
B:- since no. of replies will be limited, it will be lost among OTHER active threads.
sometimes it’s not just about traffic to a particular forum AE.
