What are Backlinks or inbondlinks?

Backlinks or inbondlinks enable you to keep track of other pages on the web that link to your posts. For instance, suppose jon writes a blog that harry finds interesting.harry then goes to his own blog and writes a post of his own about it, he linking back to jon's original post. Now jon's post will automatically show that Harry has linked to it, and it will provide a short snippet of his text and a link to his post. What it all works out to is a way of expanding the comment feature such that related discussions on other sites can be included along with the regular comments on a post.
