will try to find it in ideaplace (not very familiar with SDN , the only two things i know here is how to ask a query and other how to answer someone 
)
well the devil is in the points allotted on blogs (i think now the badges too), even if you want to have every blog posted in sdn , let them get posted , however the points (including comments and likes) should be awarded when a moderator verifies the blog otherwise it would be just a POINT-LESS blog...
in time only people who have something to add will actually blog....
