I finally got around to adding that. You can now prefill the configuration and set a "next" url so that FriendFeed can be easily integrated into a configuration flow on your own site. For example, http://friendfeed.com/settings/services/blog?url=http://myblogurl.com/&next=http://myservice.com/afteradd http://friendfeed.com/settings/services/blog?url=http://mybl... will add the blog http://myblogurl.com/ http://myblogurl.com/ and redirect the user to http://myservice.com/afteradd http://myservice.com/afteradd afterwords. There is also a "nextcancel" parameter which can be used to distinguish between success and cancel.
