The problem with Godel and friends is that they point to the limits of rationality. Without a transcendent rationality (and morality) upon which to discurse, philosophers are out of a job, so to speak. If you use logic to understand everything, the last thing you want to deal with is somebody telling you the limits to logic. So they blow him off.

At least I think the above is true for "analytic" philosophers. The "continentals", on the other hand, have been engaging in an extended attack on transcendent rationality since Nietszche who said, to paraphrase, that every transcendent metaphysics was an attempt to justify a morality, and every morality was facilitated a (usually inarticulate) "will to power." (This line sort of starts with Hegel, who posited that rationality emerged from history and the development of a collective human spirit, but wasn't "out there" before that). Godel seems like ammunition for these guys, but I don't think they have picked him up much. I guess if you are anti-rationalist, the last thing you read up on is advanced logic, even if it is so advanced it comes to its own frontier.
