The Khan Academy is a not-for-profit organization looking to provide education to anyone. With a primary focus on mathematics currently there is major expansion into other subject areas on the way. There are videos of a variety of subject areas that are insightful and can help anyone learn, or refresh on a variety of subjects. Math exercises are also available which can be used by an individual or a group of people monitored by an adult. Individual progress is tracked, badges are awarded and there is a giant knowledge map to help look ahead and the next goal.
Registration is needed for using the exercises or being a coach to track student progress.

These videos and exercises are provided in English and are directed at learners of any age. Some of the videos (but none of the exercises) are being translated into spanish. The videos are 10 to 20 minutes in length and are all made by Salman Khan, who plans on making the videos 'until he dies,' which should help him get to the subjects other than math.

As a seventh grade math teacher, I find this website invaluable. Salman Khan at least touches on every math topic we teach during the year as well as pre-requisite topics our kids should already know. Should there be gaps or loss of school time, this is another resource for students to go to and learn about whatever subject they like. The ability to set up a classroom monitoring for the math exercises could bring in another way of learning math in the computer lab and at home. Progress could be tracked and students could bounce around to any math subject they like. All the while strengthening their mathematics knowledge base.
For math, content it is set up for K-12. The other subjects are a bit behind and have no exercises at this point so its usefulness in other areas would depend on the content offered.

The quality is quite high for one individual who is using no curriculum and producing all the videos. He uses some high end products to make his videos and has an extensive math, computer science, and investment management. The videos are meant to be watched at a computer as a hope to fill in any gaps in their learning they may have. The newer videos are higher quality than some of the older ones, and while production does not rival that of other more high end sites, the videos are more than manageable and do not detract from the purpose of the website.
One blogger is deeply upset at Khan's financial knowledge and states that "[The fact that Khan] remains in this state of ignorance and go teach students about his ideas is a danger to the progress of knowledge and the general welfare of society."

Salman Kahn is the author of all the videos and the rest of his staff helps to maintain the website, design the website, and translate the content.

Point of View or Bias
This page is very biased to Salman Kahn's point of view. In his own words "The concepts are conveyed as they are understood by me, not as they are written in a textbook developed by an educational bureaucracy" (FAQ) While personal bias might not show up in many of the subjects, he defiantly could sway people to a non-partisan point of view or lead someone down the wrong path if the information he gives is incorrect.
