Cool stuff! Some random thoughts:
- APL comes to mind. As well as the classic http://www.eecg.toronto.edu/~jzhu/csc326/readings/iverson.pd...
- You might want to cross post to https://reddit.com/r/programminglanguages/.
- I like how you have a subreddit.
- I'm a little confused about how to view the source. The GitHub seems to just be a website. Is there a folder I should be looking at?
- You might want to educate people near the top on how to quickly enter symbols (control+command+spacebar on Mac OS X). I find unless a programmer is familiar with that, they are quickly turned off by symbolic languages.
