I am a big fan of open source and education so I got a domain openedtech.dev (home page under construction). The concept is that we create and aggregate educational content that is either available for commercial use with attribution, or belongs to the public domain. This is to lower the barriers in EdTech and make EdTech about services, not intellectual property.
Here is a sample of the kind of content I am trying to produce: https://www.openedtech.dev/whytypescript. I built the embedded code editor bootstrapping off of Microsoft's open source monaco editor.
I googled openedtech and found this site. Hope the similar naming is no problem, it was not intentional!
