I haven't really pull off this idea yet, so it is very preliminary. On wikia skin, content space only have a width of 600px or so. It works fine until we insert a traditional infobox. Then we only have 400px or so to write our article. I don't think such design is so good-looking, at least I fail to see such design elsewhere.
What if we change the design of the infobox, and lay it down horizontally? Does it look better that way?
An Example from the infamous Chinese Baidu Baike. The content space is almost identicle to Wikia, but the design looks more compact.
