I really didn't expect this, but Bungie's genius web team has tenderly trolled me.
After 4 years of reading and writing posts on that dark background, the sudden change to the bright white we now see was discomforting.
I complained about it for a while, until a Chrome extension was released that changed the background colour to a nice, dark grey. The feeling of being that small bit closer to the original Bungie.net colour scheme made me feel better about being here, and I was happy to post again.
Here's the surprise; I like the white background now. How does that even work?
