Ask HN: What do put on your public GitHub?

I want to polish up my GitHub as I'm currently looking for work. I currently have a few Repos on my GitHub, each with a number of forks as it's quite useful generic code - which is why I put it there in the first place.

But I have a number of little apps I've built when testing new frameworks, etc. Not anything useful that would be forked, but perhaps employers would still like to see that on my GitHub? It shows I have experience with various libraries and languages at least.

Thoughts?
