First thought is to avoid an entirely flash-based site like your 2nd example. So many, myself included, block Flash by default these days, and it has historically had runtime and compatibility issues.
Dont really have much input on what makes a good author site as opposed to any other site, honestly. The biggest piece of advice I can offer is to make sure it looks and functions equally well on touchscreens and mobile devices as it does in the various Browsers. Ive seen some sites that work and scale nicely, though many just opt for a separate Mobile version of the site bundled into their domain.
