I don't think it is bothersome. It is a trade-off between getting less traffic because there are more posts to compete with for attention or getting more traffic because there are more visitors in total. In most sub-reddits with links and self-posts, links end up dominating
In most reddits images end up dominating because that's the lowest common denominator content. In subreddits where the content is mainly articles, I don't think self posts do badly. For instance, I just checked /r/math and they seem to be more self posts on the front page than links.
You can now submit links to LW! As the rationality community has grown up, more and more content has moved off LW to other places, and so rather than trying to generate more content here we'll instead try to collect more content here. My hope is that Less Wrong becomes something like "the Rationalist RSS," where people can discover what's new and interesting without necessarily being plugged in to the various diaspora communities.
