I second this. People seem to come with a built-in affinity for probing just how amazing they are. Depending on your agenda, all you really have to do is help them explore that space.
I confess that encouraging people to talk about themselves when instead I could be talking about me is a habit I keep working to develop.
Do geeks have a greater tendency to talk about themselves than the general population, or is this pretty much everybody?
I do think that geeks have a warped idea about what normal people will think interesting. :)
