Posting Class Lectures Online

So I was chatting with my friend from the University of Florida online the other day and she told me that she was, at that moment, watching a video of her chemistry lecture that she didn't attend earlier that day. I was confused and so she explained to me that all of her lectures are video recorded and then put on to a website later that day for students who were unable to attend class to see. She said that she barely goes to class but is always able to watch her class lectures through her laptop.

I think that this is a really cool idea and wished that our school did this. There are so many times when the weather makes me want to miss class but I am forced to go since I would have no way else to learn the material my professor teaches. Posting lectures online would be so convenient to have, especially on days like Monday when it was almost 100 degrees outside! I believe that posting lectures online would improve the grades of many students because so many of my friends skip class all the time and are not able to receive the information needed for exams.

So what do you guys think about this idea? Do you think a lot of students would benefit from this? Or do you think it would cause more students to become lazy? I know that it would be hard to concentrate on an online lecture since it forces you to be on the Internet where there are tons of distractions, but would you guys like to see something like this for your large lectured classes?
