The true measure of a blog is the quality of its content, but the computers at Google have their own popularity measurement called PageRank. It’s not the only factor that determines how high your blog or website appears on web searches, but when yours increases it’s something to celebrate.
I’ve checked up the PageRank of some of the more popular D&D sites and blogs out there. This blog's PageRank is a respectable 4/10, where ten is the highest. You can check PageRank using the Google Toolbar.
All of the above sites come highly recommended. If you run a roleplaying games site or blog, how does yours fare?
