I've recently done exactly this, trying to find some posts in Economics that were just "good" and it is extremely hard to find them being made by low-ranked members--and I'm trying to help that population specifically. Unfortunately I end up giving merits to members like Hydrogen, who quotes news articles with his commentary attached. Most of the meritable replies are made by more senior members, who seem to be the only ones who can write coherent sentences.
Once I return from my tooth-pulling dentist appointment later today I'll have another look through Economics and maybe another spam section. Hopefully I'll get back before the laughing gas has worn off, else I may not be in the mood to read a bunch of BS much less give out merit for it. Maybe the dentist will give me a dose to go.
