Reddit slants neo-lib to socialist and is very pro science, so most of them are automatically put off by the political slant of some of the larger authors on steemit/minds, they'd basically need to be purged for there even to be a chance of them wanting to touch the platform. Some of the most popular authors on steemit are definitely supported by the facebook and youtube-dwelling old people conspiracy types who are the bane of redditors.
And even past that the voting mechanisms on steemit are problematic to anyone who wants equal voting power to say the least.
But it's still a good endeavor because it's one less way in which we look retarded by default to those who don't use steemit but want to see what it's about.
There are giant subreddits for anything you can imagine full of people with completely different points of view. If you look closely you can find almost any audience you want besides teen girls. I noticed a few boards devoted to female interests, but the only one I saw that gets much play is "ladyboners" ( and maybe "feminism" but I stopped going there years ago)
I'm very familiar with reddit. 2xchromosomes and mua are some female-focused subs.
