This was actually my first thought...Google users clicking a result and not seeing the tweet? Twitter wanting to capture users, but making a users first impression of the service as a bait(content) and switch(create account) right from Google results? Maybe the way its executed it won't be a big deal. Maybe the entire tweet is available in the Google results, or the log in screen will not obscure the tweet. As to the cloaking issue, Google is entering a "partnership" so Twitter is not subject to the standard rules.
