Really, I don`t see the problem.
As soon as you place your music somewhere that people can pass comment, you are bound to get totally negative stuff at some point.
It`s just something you have to accept and it kinda comes as aprt and parcel to the internet in general.

You can always put your stuff online in places like myspace, and turn comments off, if you don`t want any.

I mean, I see the point of this thread, kinda.

People in general do comment on production a lot.
Maybe it`s because everybody has a PC and thinks they can produce, so there is a lot of shite about?
Maybe it`s because production knowledge is more easily accessed, so more people know what they are on about.
Maybe it`s because some people are just buggers.
Maybe it`s because techno has some kind of expectation of being more involved, more forward thinking, and so people have higher expectations.

I don`t know. I only think that to be taken seriously, you have to work on a professional level in any part of the music biz.
