This is an unofficial translation of one of my favourite web comics, indeed the only one I follow. In addition to translating each strip, there are also notes for better understanding, especially when translation is tricky because of word play and similar. Don't forget that you can easily check the original for a parallel-text experience. A slight drawback for those of you who don't already read Chinese smoothly is that these are images, making vocabulary look-up much harder.
At the moment of writing, roughly 300 strips have been translated, including the most recent ones.
There is another version which has traditional characters here (a different translation, that is, not the same one converted): https://xkcd.tw/
