Yep, why not? Google Search Quality Team is obviously using agile development methodology, as we do. Probably they have short Sprints (iterations), with tendency to release new stuff in every 2 weeks. I guess they perform kind of A/B testings in monthly or quarterly cycles. The actual objective is to keep the search clean of spam, to provide reliable results and mainly to increase profits for their shareholders (read increase advertising revenue). Once they bring all these parameters to perfection and complete their mission, they will stop doing these ridiculous algo changes, in other words - never! ;)
They should rename the Google "Search Quality Team" to the "Search Position Extortion Team" because this is precisely what they've been doing lately.
Disgusting, monopolistic bully tactics of the worst kind. Indeed, the puppy has turned into a super monster and there is no one or anything stopping them so it seams... they own the Internet, they almost own the mobile tablets and phone market, next... probably TV and news papers...God help us all.
