Regards #2 the article doesn't give many suggestions and I'm not sure what is suggested is all that good. "the geeks want better security, more customization, and full compatibility." Assuming geeks are highly tech savvy, living at the bleeding edge, is full compatibility such a big issue? It also seems to be incompatible with security, if you're going to support legacy code you're going to be left with legacy vulnerabilities as well. I've no good suggestions for killer features but I'll know them when I see them.
