Great to see someone finally tackling this concept; It's something I have been thinking about for a while.

Having read through the whitepaper, I have a few questions...

• How will the submitted file size affect the cost to submit the URL ?
• Do you have any plans to limit the daily  block data size ?
• What controls do you plan to prevent viruses & malware being added to the library ?
• How do you plan to handle Javascript webpages which load content after the HTML has loaded ?
• How would submitting videos be handled ? YouTube webpages (for example) might be updating frequently due to likes, views etc. So a plain video submit may be preferable.
• Have you considered including an incentivised Content Approver role ? This could be used to check unverified submissions for bad content (porn,hate etc) before being flagged for inclusion by miners.
