There are several things that need to be done to improve the overall feel of the Case Wiki System (and probably more things that I haven't thought of yet), but there is one large-ish one that is bothering me... the templates.
Our first thoughts were that we would use the standard branded Case templates. MediaWiki skins of these were very nicely done for us by the ITG group in the College of Arts and Sciences. There were a lot of reasons for choosing these; most namely, that the wiki pages would be easily identifiable as Case web pages.
Unfortunately, my experience (and other's) has shown that the branded Case templates are too limiting in this aspect. Quite frankly,
750px (or so) is just too small of a width to contain a wiki page that has a lot of content – pictures and graphs, headings and sub-headings, etc. It just won't fit in the page nicely.
So, I started thinking about ways we could retain the branding but make it more flexible so all of the different types of content would fit more nicely. Wacky ideas ensued such as having the "main" wiki pages follow the branding to the letter but other pages could have per-page or per-category skins that allowed them to be more flexible. Luckily, that idea existed in my head for all of three seconds before I realized how hokey that would be.
The first "spoken aloud" idea was to change the Case branded templates ever so slightly to be a liquid layout. Remove the overall fixed width and let the page expand as necessary. This would retain the visual of the Case brand but allow for greater flexibility.
But, I started thinking that could do more harm than good. It could dilute the branding... murky the waters, so to speak, of the Case templates.
Now, I am thinking it is just time to change. What I would really like to see is something very, very similar to mock-ups Heidi Cool did for a new set of default Blog@Case templates. I really like that look and the colors, and do have plans to switch Blog@Case over to them. Plus, it gives a consistent look to the directory. I think that those pages could easily be modified to give us a flexible liquid layout; one that would work very well for Wiki@Case.
