Ah, yes, but wouldn't 2 good and 8 poor (relatively small) marketing strategies be better than 1 big (but poor) marketing strategy?

The better was join forces to avoid poor :)

The problem occurs when the stakeholders disagree about what approach is good and what approach is bad.

I'm sure you know that but let me be pragmatic, all evolution begins with disagreements, if we all agreed on everything we wouldn't have discovered the wheel yet.

Or, having various members of the community hosting town-hall type discussions, and letting the witnesses weigh in with their particular views, so that the members of the community can be better informed about which witnesses to vote for. (Maybe that's what you're talking about here? If so, then I am all-in.)

It could be, i'm not saying they should meet in a closed and secret place. We know very little about what they think about a lot of issues related to the chain. conversations between them and with the community will only help us know how to move forward together
