Very good tips not only for participants but also for conference oragnizers.
Of course, this is true of basically everybody in academia. That’s the nature of the beast, as it were– getting a Ph.D. requires you to become the World’s Leading Expert in a subject that nobody else cares about to anywhere near that extent. Getting a faculty position demands that you pursue research interests that don’t quite line up with anyone else’s (while not being too far away from the consensus of what’s interesting enough to be funded and published). We’re all unique and special here, which means none of us are actually that special, so we might as well offer whatever we have.
