There’s the site. When I was using Google Reader, the updates would always appear two at a time - one with the comic, and one with a description and link to the comic. (I guess one is a “blog” post and one is a new comic page.) Now, they don’t come paired, but instead one will come a while after the other one, and sometimes I’ll miss a comic update and I have to backtrack a day or two, only to have that update show up again a couple days later.
Not a big deal, just figured I’d post the one problem that I do regularly have. My other sites work fine for the most part.
