I am going to hold off on asking you right immediately, actually, because in this case I'm specifically trying to A/B test some constrained maximum widths that will probably look really off to you if you're used to browsing with Widescreen on. But thank you!

(I don't know if you saw my comments in the previous dw-maint post, but the thing we're suspecting is causing the issue right now is having hit a bad ratio of character-height to line-width, which is a common photosensitivity trigger -- a lot of people perceive it as being caused by "too much whitespace", but the research is starting to converge on the issue not being the whitespace but the ratio of character height to line width. Small tweaks to that ratio are usually the most effective, so if you're used to reading the site with a much longer line-width than we're testing here, it'll probably all look wonky to you no matter what.)
