Noel: your cofounder has written an excellent roundup article on marketing tactics that has gotten good engagement with your target audience. Why demolish a substantial fraction of the goodwill you were accruing with a remark like this?
In point of fact tactics are more generally useful and can be employed in a number of different situations. They need to be in service of your objective and strategy but are where the rubber meets the road.
To me the distinction between strategy and tactic is exactly the opposite of a tomato/tomato-o distinction. They exist at different levels of abstraction.
On it's own, that's not important. What is important is that many companies, especially young ones, waste a bunch of time and/or do ineffective things precisely because they haven't made this distinction, and are thinking at the wrong level of abstraction for the problem they have (if they have even managed to frame it properly).
