Various weblog authors have different criteria for including other weblogs on their blogrolls. These range from matters of common interest to frequency of updates and posts to country/geography/community relations to "you-link-me-I-link-you" policies. With the advent of syndicated newsfeeds, even blogrolls can, and are, being syndicated. OPML is one of the popular ways to syndicate a blogroll in case a weblog author wants others to be able to access the weblogs in his/her blogroll.
