Blog Heaven

Chances are, blogs (or something like them) eventually will become a mainstream source of information and marketing, consumed by nearly everyone. And blogs are just one form of social-networking tool. There are photo-sharing sites like Flickr, video-sharing sites like YouTube, wikis (user-built information sites) like Wikipedia — even virtual online worlds like Second Life. The expertise you gain from operating a good blog will position you to do well in these other places, any of which could quickly go mainstream.
