I liked hearing his voice here. Sounds like someone who's easy to relate to and available. Also shows he's "contact-able" through the site (in 2010).

After such a list, thinking a few hyperlinks might have enhanced the webtext, BUT that's also another area of the site to "maintain" and he's writing often, so...probably a wise authorial choice.

Internationally renowned context for public speaking listed first.

Lots of recent honors (past 2-3 years).

LOTS of popular, widely circulating blogs and online news sites listed here.

Invited service on a board

Communication line established. One sign of a credible site, according to the University of Maryland Libraries' criteria for establishing web site credibility

Lots of education related and enhancing identities here, e.g., parenting, web design (ed tech!), social action, etc.. He establishes a lot of authority in and beyond the classroom.

Clear, to the point, no frills, no fear.
