About four in 10 blog writers keep more than one blog, with an average of two per blogger, according to a recent study by America Online. For the report, Opinion Place, an online research site
operated by AOL's Digital Marketing Services, Inc., surveyed 600 bloggers--453 women and 147 men--in July. While most respondents--57 percent--limited themselves to writing one blog, more than one in
three--34 percent--kept between two and four blogs, while 6 percent kept beween five and seven, and 3 percent kept more than seven blogs. -- Wendy Davis
