For what it's worth, Janek is a great bloke, great player and very knowledgeable about his music. He's well worth listening to with regard to technique etc because as a pro, he knows what he's talking about, and the same can be said for Stuart Clayton too.
I personally don't always understand what some of the technical stuff means, however, the whole point is that we learn about theory and technique in order to improve, and not just look at pretty pictures of basses in the magazines avaiable.
IMO, BGM is the best bass guitar magazine available worldwide, and in the short period of time its been in print has come on in leaps and bounds, that's why I subscribe to it.
If you don't like what you see, either a; ignore the section in question, or b; don't buy the mag at all.
Playing bass is all about having fun, listening and playing music, but it's also about learning and improving, and like it or lump it, theory is a part of the learning process.
