Worker proposals are how things get done around the BitShares DAC. When each proposal reaches a threshold number of votes then bts can be released to reward the labor. My suggestion is to have a 'minor-league' of voting where both the vote requirements and the funds allowable are less.
Consider you want to print and spread flyers featuring all the great information about BitShares in your local town. This is exactly the type of action that would benefit each holder of bts and can be rewarded with treasury bts. This individual is unlikely to organize a coalition of bts voters to reach the 300 million or so bts votes required to pass a worker proposal. If the supplies for this activity cost only $10 then the individual is faced with the choice of eating the cost themselves (as many on the chain do now) or giving up the activity completely (unknown how many BitSharians were lost as a result of this structure).
Call to action: a mini-treasury fund to support projects with total expense under 5000 USD.
How many votes do you think is appropriate for these smaller projects? Several million perhaps?
