Well, I can’t say that “Being poor” is Scalzi’s best work. But I’ve read most of his SF novels, and I think they’re quite good. Especially Old Man’s War and its sequels.
Can't say what he writes is really science fiction, more like social commentary disguised as SF.
Check out his blog Whatever. When he writes about anything political it's the usual brainless regurgitation of Lib dogma. And the comments of his sycophants following are the typical echo chamber, dull as dirt.
