bengriffin 's review for:
xkcd: volume 0
by Randall Munroe
It's always nice to revisit some classic xkcd and there's plenty of goodness in here, including the House of Leaves parody. Randall's annotations and additions are a nice touch too. Considering xkcd is free entertainment 3 times a week I can't imagine any fan objecting to paying for a tangible version, especially as it's always more pleasant reading from a page instead of a screen.
