This is a Best Related Work Hugo nominee.
It's a collection of tweets from Williamson's Twitter feed. It's decently written, if you consider it as a collection of tweets.
It's not witty, informative, or in any way entertaining. Fatally for a Best Related Work Hugo nominee, it's not sf-related. The tone of it can pretty fairly be deduced from the fact of it's publisher: Patriarchy Press.
Do I have to say it? Not recommended.
