An excellent post. I've often wondered why we have a Memo key when Hive doesn't have a private messaging system. It was wise, however, to include it as it would create an opportunity for future developments.

Also, I didn't realize this:

You can safely use this key if you want to outsource management of your social network account to different people without having to worry on your funds.

As a freelance writer, this makes it super easy to sell the idea of managed Hive blogs for businesses. Some businesses might be reluctant to try Hive if they don't have a dedicated staff writer. But hiring a freelancer to manage the content without compromising financial security would be a huge boon.

I'm including this post in today's Cryptocracy newsletter, titled "Write3 Wednesday: 5 Web3 Writers You Should Know".
