I have been taking this approach for a few days: /@simplifylife/communities-and-cross-posting-made-ridiculously-simple-for-everyone
and cross-posting my own stuff, just to get more eyes on it. My logic in cross-posting to a couple of different communities is to ensure I get more visibility, not to double dip. But with the way rewards are distributed to each of the cross posts individually it seems to actually hurt me more than helping.
Big accounts are naturally going to get more cross-posts from others. Smaller accounts are going to get even more hidden by the fact that their posts are only showing up within the communities they post in.
Perhaps a solution of funneling back the cross-post's rewards to the original post (like Resteeming does) would be helpful for creators like me.
