Futurology

As you probably know from the sidebar this site was started by moderators from the r/futurology subreddit, and some of us moderate both. We initially thought most of the site's growth would come via Reddit, but it hasn't happened that way. Our main instance - c/futurology - gets most of its subscribers from elsewhere in the fediverse. Despite several attempts with pinned posts that a few thousand people have read, only 20% of our userbase joined from Reddit.

We don't want to spam the subreddit user base, but we have access to things like pinned posts and comments to promote this site.

We'd like to grow subscriber numbers for here from Reddit. Any ideas as to how to do this more successfully than we have previously?
