I feel that the top-level Announcements board that's on the top of the page is generic and basically a board for all projects.
However, if multiple industries start dominating the second, then we need to look at allowing some of them to post ANNs on other boards.
Specifically, Crypto Exchanges board should be moved so much higher up the page than it is now. It's basically dead as it currently stands. I don't think representatives even find the board.
