>> When using traditional slides, you are given a rectangle of white space to express your thought. When this rectangle is full, you have no other choice than erasing everything, and start again with a new white rectangle.

But if you scroll to far you have the same result and if you scroll less you may just use a slide where just move the bottom content to the top and add new content at the bottom.

I myself often still remember the position of the content even if I can't remember the content itself. So I can skip through the slides and only watch certain parts of it without the need to read everything.

That would be harder with that approach.
