Your current implementation...I'm not so sure it can reach nontechnical people yet. I think it sits at this middle point that makes it easy for technical people to hand off content management to nontechnical people. That's probably a good / smart way to start...but it will limit your potential audience.
Looking at the site, I don't think targeting a technology is the best approach. People aren't going to be Googling "alternatives to cpanel" to try and find you. You should be targeting people / use cases. Designers, creative agencies, IT people dealing with the marketing team, etc.
The zip a folder and upload is a great interface (A+ on giving me a sample project to try), but what I'm most interested in is how the CMS / form stuff is going to work. Unfortunately, it wasn't ready yet. I will say that adding classname is a good start, but remember try to build features in a way that it doesn't require people to edit code. Find some way to allow people to click to specify what'll be dynamic. It could use the same mechanism, just make adding the classname a thing that's done with a click and not a cursor.
The CMS / Form stuff is what's really going to sell this into organizations. Then you're going after a very large space. I think something like 45% of the Internet is powered by a CMS. 25% of that by Wordpress, something initially made for some other task. If someone gets it right, there's a lot of money to be made.
Thanks for sharing and I'll be on the look out for your fellowship application!
