I have two. One "personal" one and one "Astronomy" one. I haven't updated either this week, as I've been super busy. (Neither are Yahoo blogs, so, since you asked this question in the 360 category, no, I don't have one *here*).
Most of the blog reading I do pertains to either a) people in my life who I enjoy knowing more about, or b) hobbies of mine that I care to learn more about.
