A list of what somebody stopped paying for beats a list of recommendations almost every time. TJ Chambers mostly wrote the first kind, and it holds up better than the marketing blogs around it.
He cancelled two syndication services in the same week and explained why, including how easily the sharing could be gamed once he had spent a month inside it. He moved away from a tracking tool built by names the whole industry trusted, and said what was wrong with it instead of hinting. He looked into the past of a marketer everybody was celebrating and wrote about the fraud conviction he found. He complained at length, and without any diplomacy, about an advertising account suspended for reasons nobody would explain to him.
Then the blog wanders off completely. There is a piece on which material makes a decent homemade aquarium filter, one on receiving a state tax warrant, and several on religion and politics with no connection to any of it.
Read the cancellation posts and the tool reviews. He names people, which hardly anybody in this business does.
