Essentially, Steemit.com is just a big crowdfunding platform of sorts. I post something and supporters "pay" me by upvoting. Revenue could be raised for your project(s) by anyone wanting to by using a special tag and declaring an intention to donate the proceeds to the project.
It would be helpful if content they create for it would benefit the project some way. But doesn't really have to. An article or tutorial about node js could create funding, but also be instructional material for the school as well.
