I can't help but think the author is overly critical in seeming to view the Polymath effort as not revolutionary enough, and not including enough of the mathematics community. I view it (like I view Khan Academy) as being young and still a work-in-progress. I'm not certain it's even meant to be "revolutionary," so much as simply productive. And the author seems to want to spread the wealth of that productivity to the broader math community; I just don't know how practical that will be given the Polymath focus on highly complex problems. The author actually summarizes well though the basic potential of the Project:
"Mathematics has the greatest potential for 'doing research online'. There’s no physical entity needed and our primary standard of scientific communication is the written word. There’s nothing in mathematical research that cannot be digitalized. We will never face the problem that somebody on the other side on the net would have to actually look at our specimen, our antibody staining, our test subjects. The web works perfectly for us.In the end though the author pleads, "...please, for a change, let’s not ask Tim Gowers to do everything for us!"
Hence, mathematicians could be at the forefront of experimenting with new research activities that use the connectivity the web can offer in new and imaginative ways."
Anyway, an interesting discussion...
