I found both articles to be very informative and useful. My only little gripe about it was the compressors that they mentioned. I believe that in my mix I didn't use any of the compressors they mentioned, but I did take into account to watch for over compression and to keep a low ratio when compressing any of the tracks when mixing. Of course, I have my own go to compressors that I generally use whenever I mix in the first place, so I kept in mind some of the technical aspects of what the articles were telling me; fast attack, fast release, low ratio, make sure the sound isn't just loud (louder doesn't always mean better), etc. Overall, I would suggest that any beginning to intermediate mixing engineer should read these two articles as they have very useful information that could definitely save a mix.
