Most of this makes no sense to me.
Why update hive.blog, when so many better alternatives already exist? Wouldn't that money be better spent directing people to PeakD or Ecency?
How is a MORE complicated mobile Keychain supposed to attract people for whom existing keychain set up is already too complicated?
Why use DHF for bounties? People could raise their own funds for that.
Why target ads on legacy platforms? As you said, there is an entry barrier to joining Hive that is too complex for most legacy web users. If you're going to do targeted ads, you should be advertising on competing blockchain platforms.
Just some thoughts from a guy who thinks too much and knows too little.
