You get karma from doing things like posting videos/photos/blogs and so forth. I don't have a ton of posts, but I'd say the biggest majority of mine comes from the fact that in winters past I used to write a blog every few days about various ski related things.
Only something to be proud of if you have a high rating... I don't have a very high rating... I tend to argue about politics and religion and occasionally call people out on being an asshole.... But meh, I'd rather have an opinion than have a high rating.
