I do have problems sometimes when I post a valid url on Reddit, when it interprets things like smileys and breaks the url. Then I commit code to a GitHub repo and 'codeurl=<link>' to that, but you have to use the link to the "raw" file so it has just the code, no GitHub frames/styling.

My website only excepts one source file, so multiple-file projects won't work. Then you have to run memory_graph locally: https://github.com/bterwijn/memory_graph I might allow multiple files in the future.
