As with many DAOs the majority of votes have a low turnout and fail to reach quorum. As the project is very early there are probably many speculators wanting a quick return on tokens and there is a very low incentive to vote. A healthy community debating proposals in a reasoned manner leading to democratic votes is of high value to the project. Adding a small incentive to casting a vote - perhaps returning the gas fee with interest or a minimal amount of YFI would help build a community and engagement.
Adding a voting incentive would help to grow engagement, promote debate and voting. This would lead to a healthy community.
As the project is early it would be better to ignore short term investors solely interested in token appreciation. Engagement is likely to increase as the project shows value and this will naturally balance engagement without the need for incentivisation.
The majority of proposals fail through lack of engagement.
Incentivising voting in some way is a good idea
