That is exactly what theymos wants Merit sources to do:
It's best if sources try to exhaust their source allocations, even if it means giving posts higher amounts than is typical. If you have 150 source merit and you only see 3 merit-worthy posts in a month, then I'd rather you over-give each of them 50 merit than let the merit expire. That way there are more people capable of sending merit, and the "merit economy" is less top-down.
I have seen him try to lead by example by handing out 50 merits to good posts a few times
Certain merit sources have been doing great work too. The most noticeable are you and Suchmoon.
I think the major problem that has not been much looked into is people who receive merit, and they don't circulate it.
Also, there is unequal distribution of merit in different boards.
Sometimes one can make a very good contribution in altcoin boards or even trading or bitcoin discussion and the post will goes unnoticed because most merit sources ignore those boards. The few people who post in those boards barely have any sMerits to distribute it.
