I have a few things to add to this actually.

1. To start off, all of us witnesses have been running version 0.23.1 of Steemd for over a year now. However, it is still not part of the master branch. I found myself looking at the wrong steemd code a few weeks ago until @steemchiller clarified that I indeed was looking at the older code.
2. I feel that we need to make more people aware of the witnesses and their role in Steem. While people who have interacted with me know where to find me, there are numerous technical queries that go unanswered. For example, a couple of days ago, one user(@steemegg) expressed his concerns about the Tron bandwidth fees on @steemitblog's comment section. However, this comment was buried underneath a ton of other comments. I'm sure there are numerous other developers with queries that get buried beneath a lot of other comments. This kind of pushes developers from contributing to the platform.
3. There are a few buggy features/api's on Steemit and hivemind right now. One thing that comes into my mind is the Search feature on Steemit which does not seem to be indexed properly(I'm guessing here) for the past 6 months. Like @steemchiller says, Steemit is Steem's flagship product. We cannot have this overlooked for such a long period of time.
4. Finally, when someone new comes to steemit.com for the very first time, they land on the main trending page. We all know that this page is mainly plagued with bot-voted posts. A few days ago, I was having a chat with few witnesses as well as a few Mods from WOX community. This might be a bit tricky to implement, but if we had another filter that would disregard the bot votes and consider just the community votes for the post rankings, and make that the landing page, that might also be great for Steemit as a whole.

Eager to see what you guys think about this.
