But, I would say that they would make sense if you have a community minded guild. The blog isnt necessarily outside of guild purposes either. Creting cohesion between the different wow-content that we are providing, whether blogs, forums, irc channels, or whatever, can only increase interest along the social and traffic dimensions.
Agreed. And in saying so, that's why I'm here, associating with other bloggers. If your guild happens to be active members on your blog and in your forums, my hat's off to ya. But my guild neither knows nor wants to know about my blog. So the only reason to create one would be for other bloggers who happen to be the staple of my readership. Why do that when I can just come here?
