Since straight-up book recommendation Q&A is discouraged, book reviews seems like a perfect fit for the blog. And what self-respecting blogger would blog about a book without a link to an online shop where it could be purchased? However, this raises the thorny question of affiliate links. On the Q&A site, links to Amazon are automatically converted into links that reference Stack Exchange's affiliate ID, but the blogs have no such restriction - in theory, an author could use his own affiliate ID.
How does the community feel about our blog writers earning a bit of money when writing articles for our blogs in this fashion?
It should be noted that all articles get reviewed by a few different users before posting, and we would make it a requirement that the articles are truthful about the book (or whatever product is being reviewed). We also probably wouldn't publish too many of these kind of articles, as we don't want the blog to become just a series of sales pitches out to sell products.
