He is very difficult to categorize: he is a liberal Australian academic who is an admirer of both Keynes and Hayek, and has built upon and synthesized both of their work. He does a lot of computer simulations of economies using real-world behaviors (e.g. mark-up pricing) and has generated results and opinions that are guaranteed to annoy pretty much everyone.
He blogs at Forbes (which is funny, given his politics):
And has a great book out that takes on classical economics:
Yes, Keen does abstract from both Keynes and Hayek (who's among the less-strident Austrian School types), but neither are his primary focus.
And he did conspicuously mention Hayek.
You would be doing yourself a disservice not reading his stuff based on a blog post title.
Also I wrote "hawking". haha.
The argument itself is interesting, so let's all focus on that now.
