Blogger's Dynamic Views were introduced as a way to catch up to the new direction of the internet - something to do with HTML5 or something like that. I don't know much about these things, but if you've noticed, a lot of web property are adopting a stripped down look which is supposed to make the web faster and all. If you use Google a lot like me, you would have noticed it in Gmail, G+, Youtube, Blogger; and I noticed Amazon is the doing the same, and in their corner, so is Microsoft. Anyway, Dynamic Views was Bloggers front end answer after premiering the new backend sometime last year.
For now, it is still optional, but I can imagine that with time, it may become the only choice available. Don't get me wrong, I like it. I love that it has infinite scrolling and is faster for my readers. I also like that the reader can select various formats by which to interact with my blog. My reluctance to move yet is the minimal customization. Previously, the only thing available to differentiate one blog using Dynamic Views from the other was the background and maybe title font. Not any more.
