I've noticed on the D&D next boards a focus on 'entertaining players'.
I have to say entertaining is basically, once you realise the 'secret' of it, really really easy.
As long as you suck up to them and flatter them (subtle is best, but often enough you don't even have to be subtle), you've entertained. Done. It really requires no particular skill.
If you want to only partly entertain and partly do something else, now that's where it gets hard.
