Let's say I have enough reputation and participation on Stack Overflow or any of the Stack Exchange sites to realistically get a blog entry published, and I decide to leverage this into $.
There are many ways this might be done. For example, I might go find a lawyer to address some of the many questions about software licensing found on Programmers, quote him extensively in a post, and provide contact information for that lawyer's practice.
In exchange, I get $, or free legal advice, or some kind of valuable consideration.
Or I might do any form of product placement, in the context of an otherwise potentially useful blog entry.
Is this allowed? Should it be? Is the policy network wide or determined on a site by site basis? Is it OK if it's clearly disclosed? If it isn't (or won't) be allowed, how is it enforced?
There seems (to me) to be a little more room for exploitation on a blog entry than for a question or answer, so I was wondering what the rules are, if any.
I apologize for the many questions, but I believe they are closely related even though I couldn't find a way to make it into a coherent single uber-question.
