There's an xkcd hover text that really captures some of my feelings about people and their interests/passions:

I never trust anyone who's more excited about success than about doing the thing they want to be successful at.

This is an underlying filter for whether someone else's passion strikes me as interesting. I need a level of authenticity in the people who I interact with on any given topic.

I feel like this is the type of comment that, were it posted to one of the big sites, would've gotten reposted to the rest of them. Not unlike the original meme.
