You made a good point on knowing your blog’s audience and what they will tolerate.

If you are getting offers, I also think that you are wise to go directly through the sponsors and collect the full amount. The services often do not pay much and it is difficult to find review topics that fit with the subject matter of some blogs.

I especially agree that it is important to diversify income streams, and not rely too much on one source.

I also agree that some audiences might not accept the idea of sponsored posts.
