Hive is an interesting ecosystem for sure. There is a lot to learn for someone just joining the community. Right now, I am just sitting back, posting, reading, commenting, voting, and soaking up what I can, when I can, at the pace I can. So far I have found a couple of communities that have been welcoming and fit into. It is just a matter of learning the community norms like every other community and then trying to help make it better.
This is the way to do it. Cast the net wide enough with quality people, and the knowledge build happens very fast.
