This is going to sound trollish and perhaps I should have warmed up with something less contensious .... like the non existance of god or something. BTW:- this is a conceptual argument. not a request for help.
As a musician I have noticed that drummers always never use the internet. They go from band to band, gig to gig. The can drop into a new band easy because they never play out of tune. They have no need for technology. They are drummers. They drum. Similarly, singers usually know nothing about microphones. They sing. That's what they do. Anything else is a distraction, a deviation from their path.
A few minutes ago I read a post that asked "where are all the audio players in KDE" the answer came back "write one". It struck me that this encapsulated the problem. On one side you have the people who want to use software to get on with their main concern, being a musician, or an architect, or whatever. One the other side you have the programmers ace code writers but they know little about engieering stresses, and they think that everyone should know the ins and outs of the OS first.
6 weeks ago I started to install music software a whined to a friend that it didn't work right away and that there was no documentation, I needed to configure my system without knowing what to configure or how. He said knowingly that most of the people who would use it in Ubuntu would know about Ubuntu. Well perhaps I don't. I'm a bass player. I want to play bass. Using software is a divertion from my goal. Haveing to learn configuration is a barrier to using it, and from what I see the available software is less capable than what I was using 10 years ago in Win 95.
Why should it be? Why does music software even exist in Linux? There is no incentive to develop it but also the programmers are not musicians, so how would they know what I need? And no one is writing the manuals. While Ubunto apps as written by hobbyists it will always be this way. And thats a pity because it was a good idea and some PCs are being sold pre installed with Ubuntu. Hatred of all things MS is not sufficient to made Linux mainstream. So how is it going to jump from querky hobby to everyday plug and play?
