I agree with you - yet, till some point.
Some of the latest updates were highly necessary since quite a while and, although I also had something gone for some months (Panda) and still resting in peace (Penguin) I am sure that all those ones of us that had ...s**tty niche sites and proper good websites had to suffer a lot for the former and not that much for the latter.
Yet, again, that's not the way you fight wannabies. Because,as stated by someone else earlier in this same thread, way too many updates are generally promoting Wikipedia&Co killing some of the valuable competition these sites have. And, meh! Me no likes it too much - both from the perspective of someone living in this industry and of someone loving the Internet.
