The idea of grey literature makes no sense in the 2.0 era

The rapid progress that ICTs have introduced to our field is not always accompanied by updates of the theoretical bases that sometimes are in danger of becoming obsolete and useless. An example of this problem is the concept of "grey literature", which remains practically unchanged in the textbooks and study manuals written in Spanish. This has not been the case a: an international level, where various international conferences have been organized to update this discipline. While the attempt was noteworthy, in the current context of web 2.0 the concept does not seem justified. The traditional differentiating features used by the proponents of this idea, and many of those that have been added over time, have become obsolete. Today it makes no sense to hold on to grey literature.
