First off, welcome @phillyhistory, we are thrilled to have you here exploring the blockchain world. The Temple students (last Spring) who gifted you the account set the stage for something very exciting and we're very glad that your organization has decided to take this important leap! One that we believe to be an important avenue to explore as historical institutions enter a digital era.

You bring up some very important topics here and some you've already begun to address in creative ways!

Who is our audience? And what can we do to engage them?

Your last two posts are great examples. Simply sharing an archival image and asking the Steem community to respond is a great way to engage your readership and also begin a broader / interdisciplinary dialogue.

As you build some stake in Steem (more Steem Power makes your vote stronger), upvoting the comments and responses that you like can actually be a great incentive for your following to participate.

We're excited to explore with you!
