Regardless of how you feel about Twitter, the example is still applicable. To anyone who uses both, it is very obvious that the the latest version of the Facebook home page is very much inspired by the Twitter home page. Facebook has certainly added it's own touches to that concept, but it's hard to deny the influence that Twitter has had on Facebook.
With that said, I concur that Facebook does interactive design very well. They are a good source for inspiration for your own applications.
