The original trilogy all use the same distressed serif font for "meta". Does anyone know the significance of this font choice, when all of the rest of the design on the main trilogy sites is clean, solid lines and sans-serif fonts? Is it purposely meant to be the opposite, like an alternate universe?
When Meta.SO was first created, the team wanted the site to look different from the main Stackoverflow site so you're not confused about which site you're on. The colors on Meta site are desaturated. (This is true for all the other SE Meta sites as well)
As for the red font on Meta.SO, it was chosen so you'd look at it.
