I agree that one should not be making judgements before the "mac and cheese" is all done (but is mac and cheese ever really good?).
Anyhow, I do watch Yahoo, and for the past 2 weeks have noticed a drop in backlink counts for many sites that I monitor, including some of my own. Only sites that I know still use a link farming technique continue to show strong in Y! site explorer (BL count). Anyone see a dip in backlinks (like by almost half)? I also noticed a long delay in reindexing pages last month, now SERPs changing every 2 hours with a fresh cache. Merry X-mas (from Y!)... (unwrapping present) an algo adjustment, just what I always wanted (smirk, smirk). Actually I hope it is for the better, G needs serious competition from somewhere.
