Subjective knowledge is knowledge of our own minds, intersubjective knowledge is knowledge of other minds, and objective knowledge is knowledge of nature, i.e. natural law and the objects and events constituted by natural law. I have found this analysis very persuasive, and very useful in the interpretation of talk about subjectivity. The second type of subjectivity is the one most common to ordinary English, as in contexts like news journalism and judicial courts.
Subjective judgment is partial and objective judgment is impartial.
In this context, I don't know that there is anything to be called intersubjective. Partiality is something like sensitivity to bias or prejudice. The greater the sensitivity to our biases and prejudices, the greater our partiality. The third type of subjectivity is most current in the philosophy of consciousness. Here, subjectivity is somehow tied to privacy and objectivity to publicity.
