I wanted to check out what this link actually did, so I did a simple:
wget www.facebook.com/?redirect=somebadlink.com > site.txt
But the wget failed because of the lack of a supported user agent, and Facebook instead served me up this page.I really just had a little chuckle to myself, because, while this is extremely passive aggressive, it's not really hard to expect otherwise. I would do exactly the same if I were Facebook.

I'm just suprised that they don't link to either webkit based browsers (Chrome/Safari). You can only assume that when one of your biggest threats is Google (and MS own 1.5%~) you probably aren't going to send more users to Google's way.
All in all, it just made me laugh, since if you are going to suggest a modern browser, you surely can't ever give props to Internet Explorer ahead of any webkit based browser? IE is still struggling to implement the most basic HTML5 features.
