Affiliate Marketing Secrets

I am the proud owner of a Storyz.org, and used it a while ago as a writing-tips type blog (comparable, I think, to Daily Writing Tips, though not as popular). I had since abandoned it, but came back to it, but now I’m at a turning point.
Part of me wants to continue with the writing tips niche. Another part of me wants to elaborate on the “stories” aspect of the blog by making it a news commentary/journalist type site. I’m game for writing either niche, but want a good couple opinions on what I should do?
