Alright, I think I understand at least a little bit about you wanting it to be a bit more personalized to the Farms.
But this seems to mostly oppose the concept of it being some more formal and organized source of information.
Or at least at a certain point, too much personalization can alienate or confuse outsiders or newcomers, and I think these are mostly the people who would end up using lolcow wiki.
People who are going to use it, are people are not familiar with specific lolcows or lolcow events, and thusly not super involved in the communities or threads about them, who intentionally or unintentionally show up to read about them and be informed.
As I mentioned earlier, the most pretentious and influential interaction I can think of that the wiki might have is with an actual journalist scrolling around for information about gamergate or lolcows related to it or other web communities.
This isn't a person who shows up already knowing about Chris or Deaglenation.
I too very much like darker themes, stylistically and functionally, but I don't necessarily associate them with formal or technical information.
Anytime I'm thinking of a wiki that uses a non-standard color scheme, I'm typically thinking of some sort of fandom or video game wiki.
Where if I'm thinking of something mostly standard, it's some kind of specialized technical wiki for a language or library or wikipedia itself.
Yes, there are exceptions, but I feel like the more it looks like some default MediaWiki, the more technical and legitimate it will appear visually.
A compromise of this might be, a wiki with a white body of text, and simple colored side panels.
In hindsight the comic backdrop is a little more subtle than I remember it but it still feels strange to me depending on what the wiki is trying to do tonally.
An alternative backdrop that's more subtle but maybe still personalized is sort of a dim tiled wall of text, light gray font on dark gray back ground or something, where the casual observer may think the text is lorem ipsum, but it's really quotes from random.txt, or lines of the day, or just ridiculous lolcow jargon, or lolcow quotes, maybe tilted at a angle for flair. Like a darker subtler version of that Steve Jobs poster or something.
Just a thought.
