Which EFAP guest(s) should get invited more often?

I'm specifically thinking of guests that haven't appeared on an EFAP episode in a long time. To name a few, ThatStarWarsGirl, LiteratureDevil, AydinPaladin, etc. are just some of the older guests that I would like to see get invited again. But feel free to mention any of the "newer" guests that you like or feel are somewhat overlooked.
