I was hoping to read some thought leadership or something new, my hopes were for hour by hour optimisation or something.
I wish we could halt the herd mentality that online is always the most cost effective and accountable medium, or the predicable quote like "marketers are using online because it is more accountable" (note - it is usually only more accountable if you are blindly accepting misleading data).
I'd also suggest we should not think of online/digital as a single solution and write about it that way (as in "digital marketing is clearly the most sensible choice"). We don't say "offline marketing..." we say TV, press, outdoor, inserts, DM, etc.
Different online channels do completely different jobs at different points in the purchase funnel.
