Green Embers is one of the people I met quite early on when I joined WordPress. He is quite talented and designs headers (even did one for little ‘ol me). Check out his uber cool animated header.
He has also done some WP tutorials that I know have helped me out as I try to figure things out here. Plus he even wrote a novella himself. Like I said, GE is multi-talented and faceted and just a generally great guy. Show him some love!
And he has http://greenembersrecommends.com with a few other WP folks to review books, movies, games, etc.
