I sometimes imagine a single-blog search engine based on the model of a concordance, the special kind of index found in the back of some Bibles, which gives you every use of a key term such as "Moses" or "Mark Twain" set up in a list form like this:

• the character's first appearance in Mark Twain's novel, Tom Sawyer, published in

• choosing his distinctive pen name, Mark Twain, from a colorful phrases used on steamboats

• when the crew member called out, "Mark twain," the pilot knew the water's depth beneath

• he came down from the mountain, Moses saw that he was going to have some explaining to do

• that the water had now parted, then Moses turned and said, "Let's do this thing!" and the journey

• and so for a good number of years Moses had serious credibility as right-hand man and advisor to

With that kind of context, you know instantly which one of those you want to click on. A concordance structure could speed the use of older blog content by readers and even the reuse by the original writer who might want to reorganize the content into focused, well-developed chapters. That's my theory, anyway.
