IMHO I believe that Zcash should announce it’s grants more widely as it increases people’s confidence in the grants and the institutions.
Unless someone is actively watching Zcash Reddit sub / forums they wouldn’t know about new initiatives that are being funded.
Twitter and other community channels etc should also be deployed in these announcements to increase visibility. This will also show other talent that they can also apply for grants to develop for the Zcash eco system.
As Monero fuds the Zcash dev fee, Zcash can, by publicising the grant allocations more widely, increase confidence and let Zcash users be more aware of how the dev fee etc is being spent and get ahead of Moneros fud.
As we see here from these screenshots, Monero are always trying to spread fud around Zcash and its contributors, by publicising the grants awarded more widely, Zcash can get ahead and stay ahead of these fudders
