What's the point of sharing a post without commenting? My best experiences on Hubski have been in discussion with those whom I don't agree with. If anything, I like simply reading through what others have to say. This isn't me trying to promote the popularity of a thread, but rather I'm trying to promote discussion. If I post a link, sure, I'd like for others to see it. But it's also an invitation for you to express your opinion on the matter. Even if you agree, say something. Someone who disagrees will comment and thus a discussion is born. I don't want Hubski to become a just another link aggregator. Hubski is a place for thoughts.
