A couple of readers kindly took the time to email me and point out an epic article about what Google is up to nowadays, so how can I not mention it? Google’s Walled Garden: Are We Being Pushed Out of Our Own Digital Backyards? on Moz.com takes a look at how far we’ve come from ‘ten blue links’ on a Google results page, and whether this is all ‘fair’ to content providers. Spoiler: it ends: “I think the time has come, though, for Google to stop and think about the pact that built their nearly hundred-billion-dollar ad empire.”
Well worth a read, and the discussion in the comments is good too.
