What's with the super bright search input on black (all sites except SO)?
vs
What gives? whose bright idea was this?
Update: ok I was talking from the point of view of a user who knows where the search is and how to use it, which is apparently not very common, so I understand this design decision and can't really vote against that.
More important update:
As we've discussed in the comments, it seems like contrast helps with visibility and increases search usage, which is good for reducing duplicates and helping people find answers sooner.
But I'd like to ask the design team: why did you choose to not make the search bar as extremely noticeable on StackOverflow as on all the other SE sites? StackOverflow has most questions asked per day, and by far the most review activity than on any other SE site. How do you explain this decision?
