If you can't write, criticise... right?
That's kind of my motto. So I review and talk about books and movies and video games and comics - I pride myself on being undiscerning in that regard - for any number of online and print resources, including Strange Horizons, Starburst Magazine, The Zone SF, Hub and a couple others I can't tell you about yet.
By way of The Speculative Scotsman, I also blog. Rather a lot, I might add.
