I think it's a great system and Louie is doing a great job
Seriously, it is a very effective system. Any system that can utilize the max effort method, dynamic effort method, and repetition effort method at the same time without causing overtraining will be very effective.
The only drawback of a "pure" Westside template is that its built for the "equiped" powerlifter. "Raw" lifters will need to modify the system: for example the bench press with a bench shirt is almost all triceps, hence the ton of triceps, top range accentuation and lockout work done by the Westside crew. However, the "raw" bencher will need to put more emphasis on all portions of the movement.
It is also a system that can be tough to use if you are not a knowledgeable lifter as exercise selection is key in this program... the chosen exercises must really focus on bringing up your lagging parts.
Comming from an olympic lifting background I personally believe in "drilling" the lifts: enhancing neural efficiency by practicing the competition lift themselves quite often. This is what Russian powerlifters do (bench pressing and squating up to 6 times per week).

I don't think I will... I covered the subject somewhat in my old articles. But this subject is very complex and not entirely applicable to real life situations. At least, not in its old form.
Yes it can. Actually I did my best snatch ever in training (142.5kg) while not even training on the olympic lifts more than once per 2 weeks. At the time I was doing a ton of explosive band work and heavy band work.
