Caffeine is realted to keeping the serps loaded with the most up to date content. New content is posted in the serps in good positions (I am sure this is related to content quality) and will move downward after that.

If you will look at what the SE's are trying to do Viva indexing twitter, facebook and so forth is keep the serps from getting stale.

This now makes good quality content more important than ever, and makes us webmasters with multiple websites work that much harder.

Fresh content is a good thing just the workload and expense of maintaining multiple sites continue to rise.
