Enterprise social bookmarking. That's what I'm into. Plenty of interesting questions and opportunities. It's not going to be my main thing forever, but I've got an intuition that there's still so much benefit to find in that space.

Also, technology evangelism. I can very much see myself doing tech
evangelism for the next ten, twenty years. For that one, I need to be
close to the people I train—but the world is changing, and it's not
just North America any more. I wouldn't mind being based in Asia, for
example… ;)

I like that more than serial startups. =) As for startups: I don't
mind just convincing someone else to teach people how to get started.
I don't have to teach it myself. I just have to connect people who
want to learn with people who can and want to teach…
