I am actually a little relieved because everytime one of these interactive XKCD comic is published I wonder how does Randall find enough time to work on them, plus What If, etx.
Of course there are some people that simpliy are hyper productive, but the level of detail and complexity of these comics always made me feel a bit "inadequate" :)
