We have stock brokers, real estate brokers, autovehicle brokers in the life, and now we have information brokers in Science. A difference between this new breed of broker and old ones is that they claim themselves as scientists, instead of brokers. Naturally, these are usually not among the leading scientists, but they do survive well in the science profession.
Some critics regard science profession as another social wellfare.
If they project the science profession from such angle, I can hardly say they are wrong.
