Do you use guest publications?

I offer guest posts on my site, because I think it's an excellent way to get my audience more involved in my blog and to give people who keep my blog a focus on the talent they have. This is also an excellent way to connect with my audience, and for me that is one of the most rewarding parts of managing a blog.

From time to time, I buy a blog post from a site like SEOClerks, when I find one that I find very interesting and would like to have on my blog, but it really has to capture my interest to invest in it. However, I would not specifically pay someone to write posts on my blog regularly, because I would prefer that my invited publications and those of my real audience be the main writers of the blog.
