Guess I'll answer part of my own question ... Was regenerating the OAuth keys I use for testing and noticed that the "Connections" part of the profile is what I was missing. So on a hunch I just went to /apps with my new account and bob's-your-uncle there was the magic page.
Of course this *still* doesn't let me sign into the dev.twitter.com site - but I only wanted to do that to get to the register app page. How long has OAuth been in use and the documentation is still a mess? Sorry to be snarky but I can't imagine what someone new to twitter must go thru :/ -- Twitter developer documentation and resources: http://dev.twitter.com/doc API updates via Twitter: http://twitter.com/twitterapi Issues/Enhancements Tracker: http://code.google.com/p/twitter-api/issues/list Change your membership to this group: http://groups.google.com/group/twitter-development-talk
