HTML5 tags vs <div> just for the sanity?

Question

Other than having a structure that makes more sense (i.e wrapping a footer with a <footer> tag) why should i be using html5 tags over div tags?

If i use <div> i will still be able to use some of the sweet html5 features, so why should i worry about learning all this new tags?

P.S: I am aware of video and audio tags that make it easier to embed media

Answer 1

Using those tags will help search engine index your site, and for screen reader, etc. This is known as "semantic correctness".
