Adobe released a beta of a new service that they're calling Share today. Share allows you to easily share documents with other people. A Flex based UI allows you to upload and and manage your files (Adobe gives you 1 GB of space). Once you've uploaded them, you can easily share them with others by emailing them a link or embedding the document into a website. Documents, including PDF documents, are converted to Flash files before being shown to the user.

Here is the UI for the application:

TechCrunch has a little more on Share and the Buzzword acquisition. Other than that, there's not a lot more information about it. Its probably best to head over and try the application yourself.
