OurBigBook.com is a bit like Wikipedia but:If you are a software engineer, you can see that this is basically a cross between Wikipedia, GitHub and Stack Exchange.

- each user can have their own version of each page which cannot be edited without their permission, e.g. only
`cirosantilli`

can edit http://ourbigbook.com/cirosantilli/mathematics - you can copy and modify other users' pages, since Creative Commons license will be mandatory. You can also make suggestions to their page if you want to.
- each page has an issue tracker/comment section at the bottom to allow for sane discussion about the subject. As opposed to Wikipedia's unusable talk pages.
- more granular pages than Wikipedia: every single header has its own page/metadata, no matter how specific the topic it covers is
- you can upvote and downvote the headers/pages

For example, Ciro could have his pages organized as:

- http://ourbigbook.com/cirosantilli/mathematics "Mathematics"
- http://ourbigbook.com/cirosantilli/calculus "Calculus"
- http://ourbigbook.com/cirosantilli/limit-mathematics "Limit (mathematics)"
- http://ourbigbook.com/cirosantilli/riemann-integral "Riemann integral"
- http://ourbigbook.com/cirosantilli/intuition-behind-the-reimann-integral "Intuition behind the Reimann integral"

- http://ourbigbook.com/cirosantilli/calculus "Calculus"
- http://ourbigbook.com/cirosantilli/physics "Physics"

Then, anyone would be able to create their own version of the pages, e.g. user John Smith could create:

Here for example, John decided:

- to remove
`limit-mathematics`

from his tree - add
`derivative`

to his tree - keep
`intuition-behind-the-reimann-integral`

at Ciro's version - modify
`mathematics`

,`riemann-integral`

and`physics`

to his liking

The key intended technical innovation of the website is a PageRank-like algorithm that answers the key questions:However, Ciro has decided to leave this for phase two action plan.

- what is the best content for subject X.For example, if you are reading
`cirosantilli/riemann-integral`

and it is crap, you would be able to click the buttonVersions by other authors

which leads you to the URL: http://ourbigbook.com/subject/mathematics. This URL then contains a list of all pages people have written about the subject`mathematics`

, sorted by some algorithm, containing for example:This URL would also contain a list of issues/comments that are related to the subject. - who knows the most about subject X. This can be found by visiting: http://ourbigbook.com/users/mathematics "Top Mathematics users", which would contain the list of users sorted by the algorithm:

In some ways, Ciro wants the website to feel like a video game, where you fluidly interact with headers, comments and their metadata. If game developers can achieve impressively complicated game engines, why can't we achieve a decent amazing elearning website? :-)

Ciro predicts that the general organic user acquisition will go as follows:

- Google into rare specific subject
- look around, then login/create account with OAuth to leaves a comment or upvote
- notice that you can fork anything
- mind = KABOOM
