Can I express my opinion in opposite side?
Merit source applications are always good, because, to be qualifying enough to made application and got attention, consideration from @theymos, applicants have to choose ten high quality topics.
So, they have to spend time, to find, collect, and present them into their applications.
Is it good or bad?
It is obviously good, because some of those topics have not listed or mentioned in any list before they collected and presented in merit source applicatioins.
No matter result of application is, got accepted or rejected, it is only good for community.
One more thing, spammers should and could not apply to be a merit source. Maybe I missed something, but I have never seen spammers applied to be merit sources.
Consequently, each batch of ten-chosen-topics in Merit Source Applications are usually good topics.
