Thanks for your comments!
There are two ways of looking at it. First, the important connecting point would be why is participation important in the first place? We have seen many DAOs recently suffering from governance attacks ranging from Beanstalk to most recently, Indexed Finance and also Tornado Cash. A higher participation allows more assessment to the proposal to help to reduce malicious votes from passing. In addition, in DAOs with relatively high quorums like Uniswap, such participation help to pass votes that are beneficial. Therefore, participation contributes to both security and growth.
The second point would be there indeed can be tasks such as drafting effective or beneficial proposals if the community wants to tie to beyond participation.
I look forward to hear details, but ideally, what @noturhandle thinking should be different from what they had in AAVE where literally only one delegate was selected to receive the reward. Though their after campaign stat shares were interesting.
