Most web content is accessed via searching. People will focus on the first few results, which would promote structured content over its lesser bretheren. People, who are by definition lazy, would demand structure to minimize the search effort.

Bloggers are people and, as we have determined, are lazy. But they are blogging, which one assumes points to them being slightly less lazy than other people. Their content is there to be found and read. Adding structure that will elevate it to the attention of the interested masses seems like little extra effort in comparision to maintaining a blog. This lesser effort is needed to that ensure the greater enterprise isn’t wasted.

And isn’t laziness all about the minimization of effort?
