I agree. However i also agree with the original post that things haven't really improved that much. And i also agree that this is largely because of the adsense beast that Google created. And finally i agree that it was one of the worst things to hit the Internet.
But there is a solution outside Google's control on that....ICANN specify a minimum charge of $500 per domain name. That would a) make people think about what went on their sites more b) get rid of the hundreds of cent-earning spam sites and c) stop domainers hoarding crappy domain names.
But lets face it, thats never gonna happen. So lets get ready for the next major update. We could name it "The Groundhog Update" :)
