I know that Khan Academy has expanded to cover many, many subjects now. Khan Academy does teach grammar, which is awesome by the way. I'd also like to request that you make a section that teaches children how to read (at a basic level similar to what is offered on starfall.com). This will be useful for young children who also work on math on Khan Academy, since learning to read will allow them to understand the questions offered in the math section. So please add this feature. Thanks for everything you guys do!!
