For many Web Comic creators, just doing the comic is plenty of work; adding a bunch of additional stuff is more than they're up for. On the other hand, such basics as a cast page and an FAQ are incredibly useful in getting new and returning readers up to speed, as well as helping make complex storylines and Loads and Loads of Characters more manageable. In the end, some cast page is better than no cast page, but an updated cast page is the best of all. Fortunately, sometimes the webcomic itself is updated just as slowly.
