Two web apps were introduced.
This is a photo-sharing site by kakaku.com. It is very focused on cameras and lenses, and the photography aspect of photo-sharing. It ties in with the kakaku.com product database via their API, so that when you upload a photo you are presented with hierarchical pull-down menus that allow you to enter camera and lens information. I've noticed that other photo-sharing sites like Flickr and Photobucket also display some camera information which gets embedded into the JPEG header by the digital camera. photohito.com takes this camera / photography aspect to a different level.
This is a site for viral projects. You can set up a profile page for your project. It is then used to track buzz about said project in the media and the blogosphere.
