Presentation skills are worthy of obessive study.
Go watch Dick Hardt’s awesome 7-8 presentation on identity 2.0. This is certainly an approach and it especially works for people who don’t rank high on the kinesthetic scale.
Also, the whole problem of how a trusted identity (read: reputation) is transported from the offline world to the online world is very interesting. The Identity 2.0 blog is a good starting point on this.
