The recent branching of Nature in Nature Communications and all the Nature subject journals is confusing.
What is the difference between Nature, Nature Communications, etc. The only clear difference I see is that the subject journals are specific while the other two are not and they all have their specific IF and metrics.
Does submission to one of them preclude the submission to the others? And is Nature still seen as the most prestigious of this group or has it lost some of its appeal/importance after the creation of all these new journals. It seems that this branching would lead to 'watering down' what Nature was like.
