There are quite few misleading and incorrect comments in the blog post. So I would not use the post as gospel about color.
A couple of examples "avoid shooting JPEG unless you absolutely have no choice" - There are very valid reasons for choosing to to shoot and process in JPEG format through out a complete workflow for many people.
"(A non-compressed JPEG is effectively a TIFF or bitmap)". - Misleading: For most people the ability to use a non-compressed JPEG format is not possible, most software does not support non-compressed JPEG. Even a 100% quality JPEG in most software is a lossy compressAdditionallyoanly there are several types of TIFF formats.
And one of the most important thing he leaves out when outputting files for the viewing on a monitor of any kind - If you are outputting files in Adboe RGB or ProPhoto RGB make sure to include the color profile. For general usege sRGB would be the preferred format unless you know who will be viewing your images.
