I've stopped checking every week. I try to let my self forget about the strip for a few months so I can enjoy reading a few strips at once. Same thing with Goblins. Much prefer reading everything at once in a book, but am not that patient.
Speaking of books, it would be nice if I could get their books in Comixology or some other mobile-friendly format. Reading comics in PDF on a mobile device sucks and I don't like reading on my computer.
