Just wish to mention that our good friend Matt Cutts has posted [mattcutts.com] few lines about Update Buffy - June 2007:
historically speaking, summer is a good time to incorporate ideas into search, but I wouldn’t consider that an update myself. We do always reserve the right to tune our scoring algorithms or change the weight of different factors, even if it only affects a fraction of queries (things such as single-word queries).
