• Do you value a TRENDING NAVIGATION TAB and Why?

While I personally tend to not value the trending page...it is going to be something that we're stuck with in some fashion or another. I'd be a bit shocked if having a trending tab be available wasn't a requirement for Steemit Inc to implement this (if you were going that route...obviously if it were it's own front end, you're free to do anything.)

Now one things I would LOOOVE if you got in there was an 'Announcements' icon that linked directly to the @SteemitBlog account. Ideally showing a 'counter/icon/etc' to designate a new post being published.

• Do you value a NEW NAGIVATION TAB to discover content or is that not used?

While Steemit is great at giving huge lists of things, it's still extremely weak when it comes to the ability to search for things. Because of this, I'm all for additional ways to help people find desired content and hence a potentially new tab.

I do like your idea of the 'word bubble'...especially if this prompted the user with a refined down list of tags. If you were able to weight the 'words' based on how often it and the 'core tag' were associated could help quite a bit. (i.e. of 1000 nature posts, 100 have nature AND flower tags...giving the arbitrary weight of 10.)

• Do you ever USE “REWARDS” in the Sub Navigation of Steemit?

Yep...to check author and curation rewards. This also lends to our 'transparency' on here.

• Does viewing a HISTORY of transactions, and others Have VALUE to you?

Yep...a BIG part of our transparency.
