what i think the op ment, is - you need a method of accessing the latest page other then Book 1 -> Last (going to the last page of the archive) -> clicking on the last image.
Its 2 or three actions to check/open the latest comic, something that is i believe most common action on a comic website.
You really need a 'Latest Comic' link in the main toolbar or to sort archives in reverse order (newest first).
Oh, and the Latest Comic link under the ad is hardly noticable - in fact i did not notice it untill i read here it is there. Sides of the website are rarely looked upon, as are the areas around ads.
Perhaps make a nicely drawn Latest Comic graphic under the big erfworld on the front page? The logo kinda draws attention (but dont make the logo the link itself, no one will figure it out). Or integrate latest comic into the webpage? (i.e. show latest comic by default above the rant - thats a quite popular solution but may make the site load slower on dial-ups etc)
