I don't spend a lot of time scouring the internet for resources about squatting, but occasionally I run across really interesting and thought-provoking articles (I also run across a lot of Squat Rx plagiarized work, but that's a subject for another time...). I don't always agree with everything word for word in articles I find on the net, but always enjoy the hard work and time that has gone into thoughtful pieces. Check the following links out and let me know what you think.
