There are some big questions that remain. Such as how will companies...like indie publishers...be able to access possible clients. Facebook has corporate pages that companies can drive customers to and in return the customer gets discounts and the latest information. Currently there is no information on how if at all that will translate into their network.
All of the different means for collaboration in a centralized place make for some interesting possibilities for co-writing. Before it was sitting next to one another, sending a manuscript back and forth, or Google docs. Now there will be a several easily accessible possibilities. For example there are mass hangouts (video conferences with up to 10 people in a group chat) capabilities where groups of people can join to write a single text. Or even the use of huddles (the ability to group IM) in the production of a book.
New technology always excites me. Pretty sure it all means that I must get the new Android Tablet. It is a sign.
