This is a really cool community. After using the site for literally less than a few days, I already know most of the people you mentioned in your post.
1) Watch out for religion.
What do you mean by this? From everything I've gathered, it seems as though most users have a pretty direct relationship with reddit. If that is the case, religion (and lack thereof) is a highly discussed topic there for a lot of people. Do you mean it is taboo here, or something else entirely?
3) Some people are the smartest people they've ever met. Be careful! You might be one of these as well! I might be one of these as well (in that I act like a jerk sometimes).
That's why I follow you :)
