In general the language of internet is English but bitcointalk doesn't stop people from interacting in their local language that's how the local boards came into bitcointalk of I am not wrong.

When we talk about merit distribution its all subjective and number of active members in the community, number of sMerits they hold and number of merit sources are there even it depends how much share they got to spend in the monthly quota of their source merits.

But if you take number of posts vs merits then local boards are still ahead in the ratio when we compare with Global section so called main discussion including others as well.

By the way for which account you're talking about since this account has only 2 posts and none from Indonesian board.
