> What stops me from commenting, and from reacting to other people's comments, is the fact that the chances of starting a conversation are so low In person, a conversation is personal like this. In this discussion forum, it's common to see a chain of replies in discussion/disagreement where each replier is a different person. -- The conversation is continuous in its content, not necessarily by who is replying. People reading comments later will gain from a good comment/discussion, and may be able to offer a good reply in turn. More people read than comment, so I'd encourage you to leave a good comment anyway.
