You must examine a patent based on the specific claims, not the title. Many people make this mistake and assume the patent is much broader than it actually is.
Does not mean no patents make sense (although I have yet to see one in software in algorithms; but meaningful hardware patents are not unusual). The system needs to be completely rethought. As of now, the software patent system is not only easily abused, but itself is an abuse of common sense.

It seems to me that Ward Cunningham's WikiWikiWeb ought to be prior art, but maybe there's a technicality I'm missing, because that seems like a big one for the lawyers to miss.
I have not read a single software patent (and I have read some, if not this one) that was not completely obvious to me, and I am "one of ordinary skill in the art".
