Light VS Dark

[LadyUnicornEJG]

So I've heard it a few times, including a number of recent posts... but I'd like to know what actual, routine/repeat members think on this matter.

Should the site have a light(er) or dark(er) default theme?

Seems mostly a matter of personal preference, and I know people who prefer each...I've even updated it to where there's a quick-theme changer at the bottom of every page now. But what does everyone think?
