What bothers me is that in the humanities there are whole communities and sub-disciplines in which there is barely any real peer reviewing. These are small niche areas in which everyone knows everyone and basically the whole research is based on invited contributions and papers that are not properly blind peer reviewed - they are cursorily scanned by colleagues who know who wrote the article. In such a field there are about 5-10 journals in total and the authors jump back and forth between them. Most of them are unable to publish articles in top journals of the discipline as a whole. I personally know professors who have built a whole career on the basis of quoting themselves and by doing light editorial work. I know a cross-disciplinary field of study in the humanities that is entirely dominated by two professors, all the rest are scholars of them, and each of them wrote around 40 books, always on the same topic, and all of them more or less repeating the same two pseudo-competing themes over and over.
It's pretty sad to see these people recognized as experts when at the same time in other fields there is hard work and real progress.
