According to the title, there is no doubt that the objective of the authors is to attract attention on the state of health of quantitative studies of science (scientometrics) and encourage research vigor. Every effort in this direction is praised in any field. At the same time, it is strange that (instead of concentrating on the patient) they have extended the set of quantitative methods without considering the purpose of their application and nature of treated data. Thus, some of the statements (e.g. growing number of publications) seem to be more names imposed on facts than the facts themselves.
