Also, hashtags in kbin posts are recognised by mastodon/mblogs? At the moment, they’re not from lemmy (don’t know why). So posting out from kbin might also help in getting traction with the mastodon/mblog crowd.
One problem lemmy/kbin have at the moment for activism, is that smaller communities can get drowned out in the feed. You can of course sort by “New”, or “Hot” but might miss things, unless you’re actively checking the specific community. Same problem with mblogs too I guess.
Something interesting in the works in this regard is a Lemmy pull request to add “Best” as a feed sorting option, which ranks posts relative to their communities, and therefore should make communities equal on your feed. (See Pull Request). It isn’t finished yet but might not be far away.
