If you haven't noticed it yet, most of your material is not in text format, which means I can't search for words like "tides".
If there are an answer in your links, I would have to read like 3-4 books before I even found it. And I could risk to just find the FAQ-answer or not to find an answer at all.
So Tom, think logically, why should I do that, when you simply can tell me?
