I tend to get invited to talk about Lua ( including why I am using it ) at universities and conferences ( like, CONISLI, FLISOL, LATINOWARE ) does that counts?
Sure, although if there is an output which can be enjoyed by other people such as a paper, video/audio of the talk etc. then more people I would imagine would vote for it.
Good idea! I will see if any of the archives has a copy...
