A lack of interest in marketing is partly why you don't have a plan9-esque userspace available to you by default.
Everything you can do with Plan 9 you can do with any other system anyways, only it's marginally more tedious. If people can tolerate that, that's alright with me. What should I care how the masses do their computing? Why should I pester people about it? I don't go around arguing to people how great it is to be a pro-skub star-bellied sneech who eats their bread butter side down. Operating system evangelism and holy wars are older than the internet, and I have become very tired of them.
