Hello Matt (@freestockphotos), nice to Steem you! Your contributions are like an oasis in a Steemit community often resembling a desertifying territory, dried by the worshiped trinity of Steem, SBD and Steem Power sungods... I intend to post my first article within the next days, about an encyclopedia project, and your text would perfectly fit for the "public domain" entry :-)
Have you considered creating and promoting here on Steemit a "public domain" label (logo), or even a tag (category) to ease for the Community finding and sharing those publications?
You got my upvote, although it almost doesn't weigh anything - I'm still learning a lot about Steemit, before starting to post :-)
Thanks for the kind words! I'll consider that. I'm still getting my feet wet too and trying to figure this all out.
