Because: 1) I think what's being shown IS the fofpx.com platform. This platform has four demos, of which this is one. The others look neat too! 2) The platform looks awesome, and I'd like to use it myself for things I'm doing with kids learning math. 3) To do that, I'd need to have some basic, minimal background. For example, if I plan an activity for next week, will the web page still be up and work the same? Without that, it's not really practical to use. 4) The point of a Show HN is exactly to solicit feedback. I think any serious potential user would have the same sorts of questions. Tossing an FAQ or similar up of fofpx.com would be quick-and-easy. 5) The next step beyond that would be accounts, so people can save their work and come back to it.
