I know this is a question better suited for stackoverflow, but I'm up late on HN and this is really boggling my mind, so please bear with me. I promise it might very well boggle your mind too.<p>Take a (new) twitter url, ex. http://twitter.com/#!/ycombinator (notice the "#!")<p>Paste this link on your Facebook wall or the "What's on your mind?" input box on the main Facebook page.<p>Look at what link this resolves to. For me (and presumably you all) it is "http://twitter.com/#!/d3nidhint"<p>What gives?<p>Facebook clearly parses this url and resolves it as something different. If it can do this much, it should properly resolve the url to twitter.com/ycombinator. I searched online and came up with Google links that propose crawling these AJAX urls, but nothing having to do with this weird anomoly.<p>http://code.google.com/web/ajaxcrawling/<p>http://googlewebmastercentral.blogspot.com/2009/10/proposal-for-making-ajax-crawlable.html<p>Thoughts?
