I haven't noticed any changes to placements yet.
Caffeine likes the Web 2.0 So lots of social media and publishing a stream with Google profiles should help - https://www.google.com/accounts/ServiceLogin?service=profiles&continue=http://www.google.com/profiles/me<mpl=landing
I haven't noticed any changes... Have you? Ok, I did, I saw the results from Twitter(from few seconds ago) on first place in Google index... Is this part of caffeine?
