Yes it is hard work, you have raised several very good pointers here @arbitrarykitten
I would like to mention the use the the Social Media links in here that will connect you to other platforms to share. Not only your own posts, but posts that deserve sharing, it lets others know Steemit is working.
A little effort takes everyone a long way....
Right! Everyone share, as much as you can. Not only will it grow Steemit, but cryptocurrency visibility and subsequently comfort as well, which is a win all around :)
