TJ tends to jump mon on from one language to another.. first Ruby(when Ruby was the thing), then JS(when NodeJS became popular) and now Golang(the current "thing")

'jump' -- I doubt it was hasty. Languages have issues, why stick with one when there are plenty to choose from. Of course, I like Golang, so somewhat biased -- it just appeals to my sensibilities, perhaps it does for TJ as well.

And now he is writing a language https://github.com/tj/luna

Look at the changelog. He seems to have stopped this.

Yeah, too bad. Apex, his first go thing, is pretty great though.
