This is a problem I have with much of technical discussion, not just web. The writer focuses on details of a solution, assuming knowledge of the big picture. I'd often like the big picture, so I can have some context for the details I choose or stumble upon.

It's like reading documentation for MS Word, with every menu item explained but no clue as to how you'd put together a large, complex document. How to use every little feature, but nothing on when and why to use the features.

Please keep that in mind, writers. :)
