After a few days skulking the Meta section I realized a few important things:
#1 A huge portion of the Hero/Legendary crowd honestly care about the merit system. They are making it work, and they are more than happy to teach you.
For some basics check out this chart by Zentdex: https://bitcointalk.org/index.php?topic=2836429.0
#2 Many forum members have gone the extra-mile to statistically show you which topics/areas earn the most merit. Surprise! top Bitcointalk members prefer to merit posts in the "Bitcoin" section...Go figure.
If you have links to some topics I'm missing please post them here and I'll add them to my list! I'll keep editing it with new great info (especially statistical info) as I find it. #8 Some Merit Sources are Racist, so make sure your English is on par with native speakers
