I'm a big believer in blogs. It's a great place to show-off your hub activity and express things in long form. It's a living room for your tribe, where they can talk, consume content, and interact (both with you and fellow tribe members).
But looking at a blog as the center of the universe offends Mr. Copernicus. The customer is in the middle. Everything else, including the customer's outposts, revolves around the customer. Looking at our media outreach in another fashion is inherently unhealthy.
Context, for one.
People want different things at different times and in different places. I was thinking about this recently -- I do different things on Twitter, FriendFeed, Facebook, and I mingle with different groups, consuming and sharing different content in each network.
I'm chattier on FriendFeed and starting to use Facebook that way, too. I'm more information-driven (both as a producer and consumer) on Twitter. So companies and brands should go where the people they are seeking to attract and meet are, and package content and behave accordingly.
Because your product is always going to be one of the many (and we're talking very many for sure) a person sees in a day. Looking at a blog as the center of the universe offends Mr. Copernicus -- and it may turn off your ability to connect with customers on their own terms.
