Please note the second word of this summary is "often".

If you want to know why its "often" and not "always" visit your nearest library and take a look at the size of books on the subject.

And here lies the problem with the internet today and the comment boards such as these. People will actually walk away reading these kind of 2 minute summaries thinking they know something about the subject at hand. And on top of that you can get yourself a great rep "educating" and "informing" the public without ever actually "educating" and "informing" the public.

Which is greatly eased by dropping citations or a link, refining or contradicting what others have said - if you would care to do so. Education happens one page and one book at a time, and one can and should start anywhere. That at least some others don't understand as much as you do is inevitable; but don't disdain them for that, help them along.

I would have agreed with this view a decade ago but I don't today. I believe the internet can't be used to educate people. It's very similar to sending a kid into a gigantic library. They will be able to tell you all kinds of interesting things at the end of the day. But they don't learn anything. Despite libraries having existed for thousands of years, without a school, a teacher and a systematic process of reinforcement no one learns anything. And that's what we have been getting out of the internet a superficial class of "educated" people.

Disdain has its purpose. I probably should be using it better I will admit.
