IMNSHO, "Productivity by Design" sucks. It is vague, wishy-washy, and banal. It could be said of every web development tool from Apache to Zope. It fails to capture any of web2py's essential advantages.
Massimo's offer of "rapid web development that scales" is closer to the mark because it at least mentions one totally unique feature -- the fact that web2py scales from memory-stick to datacenter. (This is what brought it to my attention first.) Another unique feature of web2py is "it's Python all the way down" (see http://en.wikipedia.org/wiki/Turtles_all_the_way_down for the cosmological reference). Again, this is a totally unique property of web2py that no other environment can claim. I find it liberating that I only need to become proficient in Python (all right, and a little JS) to get my job done. Finally, the security model of web2py is vastly stronger than its peers. Massimo has done more to make web2py resistant to hacks, attacks, and vulnerabilities than any other platform that I'm familiar with. The familiar saw that web2py is more "productive" than other platforms is the most difficult to prove and the quickest to start flame wars. Who can say which platform is more "productive?" It is totally subjective. Someone skilled in Java development, who has never seen Python in his short life will probably not be more "productive" in web2py. Sad, but true. So how about: "web2py: scalable, pure python, and secure" -- Joe B.
