I like the idea of tags like minnowsunite; I think tags which also feature help or answers for new people would move SteemIt forward. I've seen a few unanswered questions on this platform from new people and a tag that people could use that would get answered, like steemithelp or something, would be welcome here.
I have used steem-help in this post, as I found that trending a while back. I am not sure if there is an official tag I should be using, I generally go with what is trending if I can so that it gets the most visibility.
