How exciting is this? Not that exciting : (
Its a website that aggregates Press Releases and allows you to download them in a variety of formats including a PDF formatted for the Sony Reader. Under every headline is a Sony Reader icon. Too bad the organization of the headlines seems random.
I couldn't find anything I was interested in on the site. But it does give some hope that some people are paying attention to the reader and its potential.
