I am currently researching a project concept to integrate a number of web based Open Source applications. In my googling I came across Mashable.com a Web 2.0 Mashup Treasure Trove. They are currently running a series for WordPress.
With in excess of 4.5 million monthly pageviews, Mashable is the world's largest blog on social networking.
It covers sites like MySpace, Facebook, Friendster, hi5, Piczo, Bebo and YouTube, but also other independent web applications.
