I very happily switched to the note-taking app Roam recently. Some weeks earlier my friend recommended it to me and because of too-much-to-do I almost didn't look at it. I wished he would have offered me a bet that I will want to switch after trying it (e.g. for a week). Then he would've profited from his knowledge, and I would've had a greater incentive to try it. I wondered if I should offer this bet to any EA, because I believe there is maybe like a 20% chance that a random EA would happily switch (though the subgroup of EAs that would be willing to take the bet probably is not a random sample of EAs).

What do you think about this bet, or bets like this in general? How would you concretely offer it?
