This doesn't meant that good writing will be any less appreciated. While I understand where you are coming from, look at photography as an example -- for the most part becoming a "photographer" is entirely trivial with digital, high-quality camera available at reasonable prices. Whereas even 10 years ago it was tough to casually become a photographer because of what was necessary to develop and print your own work.

This doesn't mean people don't value good photography any less. And the same will apply to writing, or any other creative/skill based artform -- ubiquity doesn't mean the death of taste or value, IMO.
