PG, since you publish your "talks" as essays anyway, why don't you use your talks to tell interesting stories (from YC or other times of your life)? As you already pointed out, it's better for the audience too to read your essays and think carefully about the ideas, rather than react in a linear fashion with the rest of the crowd.

Stories, on the other hand, like "How YC started" would be much more engaging to hear from you than read. The content of the stories should be interesting enough ("Never a dull moment?"), so that you don't have to make any extra effort to seem interesting.
