I've been pleasantly surprised with some of the recent content of Wikipedia. Court cases such as In re Bilski have been reported with useful summaries and discussion. The Wikipedia summary of In re Bilski, in fact, is recommended reading for those interested in the evolution of "business method patents."
Meanwhile, the impact of the decision may be growing. See "BPAI Applies Bilski to Deny Patentability of Machine Claim," where the Patently Obvious blog reports on a case where the machine aspect of the In re Bilski decision may be more demanding that I would have thought.
