Read/Write Web has a list of . . . lists. All containing information about Web2.0 sites springing up like daisies around the internet.
What’s a Web2.0 site you ask? It’s one of those good-looking, fancy acting websites you’ve probably seen around. The developer of these sites use more acronyms than before, like AJAX, JSON, etc that allow users to interact in ways they couldn’t a couple of years ago. Some of these sites are so cool they drop vowels from their names – Flickr and HappyCodr are a couple of examples.
Overall they still need content and community but some of them are just beautiful to look at and fun to play with.
