I think you need to work on the communication of what this does, and why it's different from data flow languages or spreadsheets. Putting formula in cells and using that to calculate things feels _very_ spreadsheet like, and having results depend on others feels _very_ data flow like.

Don't just say things like, "You can't program in spreadsheets," build examples showing what the other system can do and its limitations, and then show how what you've built can go further.
