Blogger launched in March five blog views that used cutting-edge technologies to transform a blog into a Web app. Back then, visitors had to enter a special URL like gmailblog.blogspot.com/view/sidebar or install a Chrome extension to switch to one of the new interfaces. Six months later, Blogger created two new views (classic and magazine) and added the list of dynamic views to Blogger's template editing section so that blog authors can replace their template with one of the seven views that are now available.
There are three kinds of dynamic views: photo-oriented templates (flipcard, mosaic, snapshot), text-oriented templates (classic, sidebar) and magazine-like templates (magazine, timeslide). If you don't have a photoblog, classic, sidebar and magazine are the best dynamic views for your blog. Blogger's new templates bring a lot cool features and change the way readers interact with a blog. Infinite scrolling replaces pagination, blog posts are loaded using AJAX, Blogger caches blog posts so they load faster, images are downloaded as you browse, you can use keyboard shortcuts (j/k or n/p) to go to the next or previous post just like in Google Reader. There's also instant search that shows the list of results as you type.
I don't intend to switch to one of the dynamic views, but my favorite templates are sidebar and magazine. You can always bookmark these links or use Google's Chrome extension, which needs to be updated to add support for the two new dynamic views. Some Google blogs have already switched to the new templates: Blogger Buzz, Gmail Blog, Google Docs Blog and LatLong.
