@Emil,
There is an excellent blog-site 'Methods of Projection' that not only has some good discussion on Wittgenstein, but also has many useful links.
Unfortunately, the blogger has decided to stop posting. But he is leaving the site up for a while longer and the links are still working.
The blog-site is located here:
Methods of Projection
Also, a number of Peter Hacker's articles were linked to in the original post. Here's the link to his homepage:
Dr PMS Hacker Many more articles can be found there along with a recording of a debate between him, D. Dennett and J.R. Searle.
He was involved in the latest (4th) edition of "Philosophical Investigations"
and is considered to be one of the leading authorities on the philosophy of Wittgenstein.
