Most of the top sites in my niche are old and outdated but generate insane amounts of revenue (mostly affiliated no G ads).They still have the 80s layout and kw density of 15% and over. Most of their links are partnered/exchanged and the information is just crap a 10yrs old can write something more catchy and informative.
I think once G resolves this problem they will move a step forward in a good way. That might be a good reset for the serps and a breath of fresh air for webmasters and users.
Let those old fat dogs work a little this time.
