Hi and Welcome to ATP!
I totally agree with you. Though I think all the "how to" posts should have something in the subject line of as to level of information. Photography 101 to my mind was about how to access and use all the features on your camera - the mechanics. Ideally keep it short and to the point with weekly installments so people would have time to get comfortable using a specific feature. Information overload in a beginning course in my experience tends to make people tune out.
Your post, Photography 050: Light – ISO, Aperture, and Shutter Speed and Dirtdorphins, How I learned about F-stops is very far from basic. Both belong in a more advanced category in my opinion and I'm in awe of all the clear information and examples in both posts. But as I already knew a lot of what you both were writing about it was easy for me to read and understand.
Since this thread is about photography, I think each post should reflect on the Subject Line the level of knowledge being covered.
