My recommendation for BD User, if you want to get many merits, just keep using the Meta board. Historically, this is where merit sources spend most of their merits.
I wanted to know if that was true or not so I consulted DdmrDdmr's
Merit Dashboard & these are the top 10 most merited subsections of the forum since the inception of the merit system:
Economics - 13.45% of total merit
Marketplace - 12.12%
Meta - 9.54%
Russian - 7.75%
Dev & Tech Discussion - 6.87%
Bitcoin Discussion - 6.18%
Trading Discussion - 5.43%
Beginners & Help - 4.28%
German - 3.93%
Turkish - 3.53%
So Meta is actually the 3rd largest subsection for merits -- whether or not it is more popular than this among merit sources, I'm not totally certain.
Nice data. However, you must be careful.
Economics is basically WO thread, nobody really gets merits in other threads there.
I dont know about marketplace, maybe ANN topics.
So, out of WO, meta is the second place.
