Kindle owners longing for the ability to share their fave passages with the world only have to endure a few more agonizing weeks of reading in isolation.  Announced in April, the now “socially aware” firmware version 2.5 for the Kindle is expected to hit Kindle devices in the upcoming weeks. This latest firmware will include facebook and twitter integration, expanded font selection, on device password protection, and improved support for PDFs.  The update will be delivered over the air for those in the Whispernet coverage area, while those lacking in the 3G department can point their browsers to Amazon and install the update manually. No need to proclaim the arrival of the update to the world as everyone will know when book spam passages begin to hit their twitter feed.
