I never really took a close look until you mentioned it now. But that is an interesting question. I am not 100 percent positive, but it looks like a San Serif style font-possibly 14 point. This is usually what is used when an author writes or types out his or her individual chapters of their published books. At least I think that this is the font and style they utilize within. And apparently hubpages team employed the same or similar format. Hope this helps answer your question somewhat.
