Good article! The main thing I didn't quite agree with was the blanket statement that GIFs should never be used. I fully agree that they shouldn't be used for video clips, and I understand this was the main context, but for small animations (especially pixel-art types) they're still a good format.

I also found them useful recently for small (28x28px) thumbnail images on my personal website. On average, saved as a PNG the thumbnails were 20kb, as a JPEG 9kb, and as an optimized GIF about 1-2kb. With about 100 thumbnails on one of the pages, the savings are pretty significant. (At least, this seemed to be the best approach; if anyone with more knowledge of image compression has a better suggestion, please let me know).
