Thanks for posting this. Interesting read but I do have a few questions.
1) Is you blog focused on one particular niche say, for example, painting?
2) Are you the only author of the blog?
3) Borrowing "writing about a common topic" from diberry, don't you ever write about such common topics in your blog?
4) Are all articles on your site completely unique as you say in your example. i.e. does each article on your blog is the first to say something unique on the topic like "the best way to paint a rock is to use white latex paint"?
5) Do you provide any value add, other the article, on your blog which such brand cheaters don't have or reproduce?
