What is interesting?

Robin Hanson against sophistication:

Interesting folks, in contrast, get so far into a particular topic that they become at risk of violating conversation etiquette, by talking too enthusiastically for too long on topics of minor interest to sophisticates. Yes, interesting folk are at risk of being distracted from dress or hygiene, or from carefully climbing their local status ladder. But they are also at risk of making a unique contribution to the world.
