Which skills do you think you learned from Fluther?

I think apart from brushing up English (of course), I learned about critical thinking and how to defend my opinion. I don’t mean how to argue, but how to stick to my opinion and not to be swayed by others when I’m sure I’m right. The skill can be helpful when I need to distinguish the right from the wrong. I also learn how to make a constructive and civil argument.

Do you learn, or brush up, any skills on Fluther?
