Is this Beta Software? Not anymore. We're calling it 1.0.0 and saying it is ready for others to use. It has been in use for a couple years internally with the Smartdown team.
Is this open source? Yes, finally. As of April 28, 2019 Smartdown has been released as open source under the BSD-3-Clause license.
How are you going to make a living off of this? I have no idea! Smartdown is something I want to exist. I'm hoping that someone else finds it useful and that maybe there will be a way for me to keep working on it. Right now, it's a weekend and spare time project.
How can I provide feedback? - Send an email to smartdown@quantumclay.com; any feedback is appreciated. I am working on creating a more flexible and interactive means of user feedback.
What is InfoClay? InfoClay is the name of an interactive authoring environment wherein Smartdown was initially conceived, and then isolated as a separate library. InfoClay is still under development as KnowBench, but my priorities have been on stabilizing and releasing Smartdown. In some of the earlier documentation and examples, InfoClay and Smartdown mean the same thing: markdown-based, interactive, reactive explorable explanations.
