I’m also in favor of incentivizing delegation.
Since the Snapshot Delegation User Guide was published 8 days ago, we had 10 people listing their address as delegates and 7 wallets that actually delegated their $INDEX to some of the delegates. So there’s definitely potential for improvement and we can assume that incentivizing delegation is a good motivator to do so.
Regarding the amount, I’d say that the minimum is set by the gas costs which occur when delegating and the max amount is probably so that it’s still fair compared to what a contributor can earn for “small tasks”, 50-100$ seems fair.
I’d also like to see more community contributors list their address as delegates, as with only 10 I’m sharing the concern raised by @oneski22.
