I came to darktable website to learn what darktable does not that there is another piece software that I do not know which does a somewhat similar thing but in a different manner.
not only this is not helping the clueless visitor, but it is advertising a major competitor and shows your software as being inferior to this commercial competitor.
IMHO not mentioning lightroom is a smart move, I discovered darktable without having any knowledge of lightroom for the simple reason that adode products do not exist on Linux. Also I should mention that I use darktable as an alternative to gimp which I chose as an alternative to photoshop 5 when I made the switch to linux.
This to point out that you should not presume of how people use software either, expecially with software that can cover some many different uses as photoshop.
