what they mean; it is not memory but judgment .”~ James Russell Lowell

• 100+ billion static web pages are publicly-available. These pages can
easily be found by Google and other search engines
• 11+ billion static pages are hidden from the public. As private intranet
content, these are the corporate pages that are only open to
employees of specific companies.

Google.
