I have often wanted this. Lots of times. And I know how to add it to a specific template. But what I would like to see would be this feature added to the core. It might look like
"Don kicks Garvin's ass in photography" <= entry title (like an h2 or so)
"Don shares his secrets to best lenses and camera bodies" <= proposed entry subtitle/byline. (h3)
Thoughts?
Disclaimer: Garvin has already forgotten more about photography than I will ever know!!!!
