Poll results seem quite clear - majority of our respondents were satisfied with the black background. Thus, we won't be changing it.
Since there was a big minority who still wanted a different background, we'll be providing an opportunity to read the blog in white. We've changed the mobile view of the blog so that it shows white background. "But I am reading it with an ordinary computer!" Don't worry! You can easily choose to read the blog through the mobile view just by adding ?m=1 to the end of the blog URL. So in principle, everyone wins. Isn't that just dandy!
