Best web 2.0 websites

Emily Chang - eHub Web 2.0 is the network as platform, spanning all connected devices; Web 2.0 applications are those that make the most of the intrinsic advantages of that platform: delivering software as a continually-updated service that gets better the more people use it, consuming and remixing data from multiple sources, including individual users, while providing their own data and services in a form that allows remixing by others, creating network effects through an "architecture of participation," and going beyond the page metaphor of Web 1.0 to deliver rich user experiences. EmilyeHub is a resource of web applications, services, resources, blogs or sites that I'm using, find compelling or notable. I'm online every day and this list is updated whenever something comes in while surfing, via email, RSS reader, SMS or search. I'm particularly interested in next generation web (web 2.0), social software, Ruby on Rails, Ajax, blogging, location mapping, open source, folksonomy, tagging, design, and digital media sharing, so this resource has that point of view.
