This sounds like blogging to a specialized audience -- which only works to your professional benefit when you blog for the ones who pay you (maybe indirectly by blogging to your professional peers). It indicates a hierarchization of communication: you can only reach those you already "won". A somewhat related problem for blogs nowadays is that policing spam takes a lot of time and effort -- you depend on the big platforms for that if you don’t have a lot of time. The web became a much more hostile place, to the big players’ benefit. That removes low-overhead communication among peers from the benefit of blogs.
