I use this blog (and the sister blog drureviews.blogspot.com) for my SEO articles I have written in the past. I am always looking for new subjects to write about.
I will write 250-300 words about a particular subject.
I have written about any number of subjects and am open to writing about anything except adult subjects (since Chikita does not allow that ala ToS).
Limitations - Explicit Adult related subjects
