There is also a skewed distribution of the gender and age of blog authors in
relation to blog type. In a recent study, Herring, Scheidt, Bonus and
Wright (2004) found evidence of three basic types of weblogs: the content of
filters is external to the blogger (links to world events, online happenings,
etc.), while the content of personal journals is internal (the blogger's
thoughts and internal workings), and k(nowledge)-logs are repositories
of information and observations with a typically technological focus. In the
present study, we coded each blog in the sample as journal, filter, k-log, or
mixed (a combination of two or all of the first three types).
