About decay vote. I think proxy votes should expire. Because if some people want only to use hive for games/content, they can proxy their vote.
I think there don't vote again if it expires. If they proxy their vote to someone they trust, it should be perfectly fine.
Only the voter should expire if he is inactive. Like 6 months no witness or DAO votes/changes = expire.
That should be work because then the inactive people cant block anything.
And as an alternative, if they want to be inactive, they can proxy. So it's more political like they vote for a middleman that is looking for their interests.
It can also be work that way, that many holders combine their vote, to get more attention for changes/ ideas.
Edit: Btw I love the roadmap. That is what I was looking for for a long time.
Also if at some point a front end should be as easy as a WordPress installation, nobody can stop hive ( I know that would be way more work :)).
