The full version of my answer is here, I'm not going to repeat myself, and I also read your other post.
About this post, I totally agree with you, I stand by what I said in my other answer. I just want to comment on this:
We need to get rid of this tech support impression. We're not tech support. We're here to help solve problems on a working Ubuntu, not fix a broken one. We're here to answer questions about how to use Ubuntu, not how to debug it.
Linux mint forums got tired of "debugging questions" too, you could go there and have a look, Elementary OS moderators got tired too, and guess what? Both forums died. You know why? Because all Ubuntu based distros are known as "the beginner distros"
Zorine, mint, Ubuntu, Elementary, you name it, and if you don't believe me, go to youtube, and type "zorine distro review" or any ubuntu distro, watch any video, the guy who's doing the review, will give you a big smile and say "If you're a beginner, I definitely recommend this distro, they have a great community, you will never be left in the dark!"
Who's to blame? no one. So you think, I like Ubuntu? No way! I like Crunchbang and Manjaro, installed Ubuntu, because I wanted to make sure, that if I got an error (and I do get many errors), there's someone to help me.
Now you say, that I should debug my problems? Debugging would require me to read all the basic linux command, and understand what modules are loaded and how my system works. Well, in that case I go for Arch or Manjaro, get a bleeding edge distro, not having to worry about updating my system, and at least I get to show off on IRC on how I customized my OpenBox or written my own window manager.
If Ubuntu loses its tech support, it looses everything. This why people would go for Opensuse, this why people prefer Red Hat over Centos: Tech Support.
About your second question, duplicates, low quality questions and stuff: this is why I'm considering to leave AskUbuntu, I left many forums and Q&A sites because of that, and I might leave this site as well. Maybe I will only ask, but it's really boring to answer some questions and to flag and so on. God bless the mods, they are doing a good job in this environment.
