I mentioned a bit further back in the thread, our traffic has stabilised near its previous level, but with a lower ranking across more keywords. That may indirectly support this theory. In theory with caffeine its possible we are getting more pages returned across all the long tail keywords we rank for, but they are perhaps being ranked slightly lower than before. Therefore some space has been created for other (perhaps a greater variety of) sites up in the top 5 or so spots (we previously tended to rank 4-6 for our main keywords, whereas it now appears to be 6+). Admittedly that's a generalisation across a lot of long tail keywords, and it always struck me as odd how few of these keywords appeared any higher than position 4.
