Ask HN: Best back-tweet tracker? Tweetmeme is killing topsy/backtype

I'm looking for a way to grab and display all tweets linking back to a given URL. Backtype and Topsy both claim to do this, while Tweetmeme will tell you how many tweets link to a URL but not give you the tweets. This is unfortunate because Tweetmeme appears superior to the other two: Comparison: http://tc50tweets.techcrunch.com/story/556640499/tribune-co-sued-by-patent-troll-for-10-million-over-how-it-links-to-stuff-windycitizencom http://topsy.com/tb/www.windycitizen.com/chicago/business/2010/02/10/tribune-co-sued-by-patent-troll-10-million-over-how-links-to-stuff http://www.backtype.com/connect/www.windycitizen.com%25252fchicago%25252fbusiness%25252f2010%25252f02%25252f10%25252ftribune-co-sued-by-patent-troll-10-million-over-how-links-to-stuff Tweetmeme found 14 tweets linking to that URL while the other two services only returned 3. Tweetmeme doesn't let me grab those tweets programmatically. Are there any other services that return 14 who will?
