I am a big fan of Readymag animations, we use them all the time in our brand documents. It helps make them a bit more than just a flat PDF!
Secondly, we really like having our own subdomains—so that when documents are sent, they have our branding instead of a hosted link or a lengthy Google/Dropbox URL.
Finally, their new type interface is a big deal: being able to go in and select individual glyphs makes it perfect for our branding work.
