I got annoyed by the total size of my website, so I finally decided to optimize it a little bit. The main problem was that a few pics and gifs weighed 10 times more than everything else combined. I switched gifs to pics and dithered everything else, so now the website weighs about 2 MB instead of 500 MB. These changes probably caused some posts to reappear in RSS feeds - sorry about that! But now my soul is at peace again :)
