Multimedia publishing just got a little more enhanced...at least if you have an iPad.
Soon you'll be able to view Twitter conversations (called "hashtags") within an eBook you're reading. Arcade Sunshine Media published an enhanced eBook with these functions: Here on Earth: A Natural History of the Planet by Tim Flannery.
You have to download the application for Here on Earth, then you can access the tweets plus some other cool stuff. The application also allows you to copy text and, best of all (in my opinion), make notes on the digital page (much like writing in the margins).
Click here to download Here on Earth and find out how to use the Twitter hashtags and digital notes.
