Good stuff to brand it on Hive :)
It would cost a lot to create a proposal with such a distant end_date
IMO it is good to have some costs to prevent spam.
But I'm more a fan of " hire fast - fire fast". I also think the price is too high for microtasks.
Low-cost proposals and more of them are IMO much better than expensive ones and only some. 10$ is IMO good spam protection, and to hide the spam a downvote/hide vote would work IMO.
I would like more a mentality of "let's try things out" and if they doesn't work after some time period, defund.
I think we have a lot of know-how in our community from different topics. To get the potential out of it we should be more open to funding some things.
I think it is close to impossible to get a 20$ a day proposal get funded. But in these can be a lot of long term value.
