What is usually stated is that the important point of Badiou's philosophical construction is the now famous equation ontology = mathematics. The tendency is to present this as a strictly original philosophical proposition, which continues the materialist line of thought beginning with the Platonic break and continuing through Galileo and restated by Badiou. This, it appears, rather misses what I suspect is the central trajectory of the text � that Being & Event is centrally written against Heidgger�s Being and Time. To avoid this issue is to avoid the central monumentalist intention of the book. Perhaps it seems a little naive to say, to suggest that Being & Event is in the now substantial line of attempts to write responses that are to supplant Heidegger's Being & Time, a list that includes Sartre's Being and Nothingness and Adorno's Negative Dialectics amongst others, but this central reactiveness of the text has not been discussed, probably because the idea of comparing B&E and B&T is simply to horrible a thought.
Both the driftwork site and the maverick site are interesting.
Since I'm currently making an argument that metaphysics is unintelligible, and am using phenomenology to do it, I don't think that either Adorno or Badiou are going to be helpful.
But let me see. If my thought gets confused, I may start reading these new guys. I don't believe that they are seminal like Heidegger and Sartre.
I'm not up on Badiou. In what way is Badiou's equation of mathematics and ontology different from Heidegger's equation of the same? As I understand it Heidegger does this more or less on the basis of Kant's notion of the a priori, perhaps misunderstood (or reinscribed) somewhat. I find Heidegger's use rather compelling, especially when considered in science.
Adorno is easy bracket out. Just as the world can be divided into continental and logical-positivist philosphers, so to can it be divided into Adorno admiring Hegelian/Marxist dialecticians who don't understand Heidegger, and everyone else.
I haven't read Badiou. He's one of the new thinkers (Giorgio Agamben being the other) popular with the critical thinking crowd. I understand that by "mathematics", he applies set theory to ontology. Sounds promising, as that should scare most literary theorists to a respectful distance. He may be the Edgar Codd of philosophy.
