ObviousIdea is working currently on 2 web apps
Send-To-My-Cloud one is a online bookmark manager, to keep a trace of the web sites you like, be able to read them offline ( to come ).
Integration is done by a plugin with your browser, and extended by clients for your mobile ( iPad, iPhone to come ). You can use it already, with a complete free account and extensions for Google Chrome, Firefox, Safari ( soon ), Internet Explorer ( beta )
The 2nd project with pure online activity is photolikr, it is still under development, the purpose is to be able to do social rating and sorting of your photos, whatever you host them with Picasa Web album, and later with Flickr or another hosting service
