Scott Kurtz has a new version of the PvP website coming – it's nice and he had professional help so I'm sure it'll have some cool bells n' whistles on it. I especially liked the way he did the about page – any serialized webcomic that has been around long enough (say 500 or more strips in the archives) is intimidating to a new reader on some level. You need an about page that really communicates your overall strip to the new reader.
This post reminds me of a question I've been meaning to ask though – which is: Should webcomic websites be an artistic extension of the comic (think about the new Perry Bible Fellowship Site or Herzog the Vile), essentially extending the look and feel of the comic or is that not that important? I think functionality of the website is really important but I also suspect that many more people then currently do can have both functionality and look and feel.
