All - Per issue 1263 (http://code.google.com/p/twitter-api/issues/detail?id=1263) (and the OAuth spec), we're looking to change the Content-Type header for OAuth token exchanges to 'application/x-www-form-urlencoded'. To date it has been 'text/html'. We want to ensure that this will not break existing applications, so if you have any qualms please voice them here.
