Here are two strategies for finding blogs:
Start on the home pages of Blogger.com, Weblogs.com or MovableType.org for a list of recently updated weblogs. Click on a link to one of these blogs, and browse the recent entries. Look on the side of the page for a blogroll, a list of other weblogs that this author reads. Part of the fun of weblogs is to read a bit, click to another blog, read a bit, and click on.
Or, you can start on the EatonWeb Portal, a listing of more than 16,000 weblogs.
To find photoblogs, start on Photoblogs.org.
