Great, thanks for sharing your passion - it's true that Hive's rewards system means that some people become intimidated and believe that they cannot compete or that it will be too hard or a waste of their time. So promoting Hive is often as much about helping people to become the best versions of themselves as it is about the technology or money.
Listnerds looks interesting, yes - we will take a look at it in time and think of ideas for using it to promote Hive on a large scale.
I had an entire post talking about that problem. While it is still true, in my opinion. Someone pointed out that "If you build it, they will come", a point with which I agree.
That's the essence of what @thisismylife and I are trying to do. Filling missing spaces/communities can be a great promotional tool in itself as from personal experience I have seen people not opting to join would do so because they don't find their niche.
This will also coincide with another community set to be there solely to be a guide to all the active communities, making access easier. So many people are not aware that the type of community they're looking for already exists.
I have actually spent hours going through all the communities and categorizing them, we have over 400 active communities (Based on pending rewards at least), so I think the guide we're working on could serve as a great meet-up point that will not only shed light on existing communities but make creating new ones more purposeful and focused.
