One of my favorite feelings is seeing my articles get published. It feels like I accomplished something in my day because I put a lot work in creating good information that I believe will help others out someway. I don't mind them being up for a little time, but I get discouraged when they get bumped down because once you hit refresh, you see 6+ articles listed from top to bottom that shout "READ ME! READ ME!" that 'written' by the same person.
So you read one of their articles, and their articles don't really give you a lot good information. It feels more like a 'sales page.' What's worse is that each of them are directed straight to the merchant's page, while other writers don't get that privilege. (I know some people will say, but don't worry a presale's webpage are better for conversations anyway. But there are good writer's out there that know how to blend language into anything having the option of writing a good, quality article, and directing them to a merchant's website wouldn't be a asset that's bad to have.
Anyway the point is, I just feel like these type of articles not only saturate the quality of other articles, but the market as well.
