What I'd like are three options on the home page, the category page, and the search results page, and you could even let the reader change to their preference.
1.) Show full posts (same as now)
2.) Show just a list of titles + links to posts (this is what I want Google to see, btw)
3.) Show list of list of titles + links as the page's "table of contents" and then the full posts below the TOC. There should be two links per title in the TOC; one of open the post and the other to just down to the post saying on the same page (using a URL fragment.)
