Big Picture

When someone leaves a comment with a URL Post Snap goes to their website and looks for a syndication feed. If it finds one it finds the author and title and date/time of their most recent blog post, then adds a little bit about that post to their comment.

If the URL provided is wrong nothing happens. If Post Snap can't find a feed nothing happens. If it can't find an author and a title and a date/time of publication nothing happens.
