Best way to see who's linking to a URL?
brandnewlow: Sorry.  I think I totally botched this post.I'm looking for a way to automatically look up any sites linking to a given URL.I'm building a memetracker and while I've got the related stories and clumping of them in hand, tracking down the discussion links in the way that Techmeme does it is proving much harder to do.I was wondering if there was a way to do it other than Cosmos.  And if not, what would be involved in creating something that does that?  Building a web spider?
