When Heaven Inspires Complex Holography
Yup, this is my favorite Witch: the young lady whose biggest hobby is "Light Reading". Hermione would probably have a field day on the Internet too, since the amount of reading possible there is huge! Of course the web needs a lot of common sense and a couple of tons of discernment, but at least the information is there to build your knowledge with ever accelerating speed.
As for the other 'which', with every information you receive, the first question when receiving conflicting information should be: "which of this is true?" Does it jive with what you've built as knowledge thus far, or can it possibly make you realise a new gem of knowledge which clarifies your 'Lust for Clarity'?
