I could personally take or leave live readings of Wikipedia. I wouldn't do it, but I have also gone on my share of solo wiki binges. There's no problem with learning about things. The thing that bothers me is a room full of people with shallow knowledge of a subject who talk over anybody else. I think it's fine to care about things, but I need other people to be able to tune their volume to their level of knowledge and understanding, which you really can't do if you think you know everything.
