Zyeriis: The problem of the average user not being able to adjust their CSS is a key one. We are trying to make Wikia work for as many people as possible - so that the majority don't have to know how to use CSS to make their experience better. There are lots of stats you can find about common screen resolutions Wikipedia for example says that around 24% of Internet users have 1024x768 or less. You are right that this will vary from site to site (and wiki to wiki), but one of the other aims is to increase consistency in the interface... again with the intention of helping those "average users".
