Online Photo, Bookmark, Data Sharing and Tagging

There are many Web 2.0 applications that involve sharing files, photos, bookmarks, audio -- or even just storing those files as a backup in case your computer or website crashes. Some of these sites also allow folksonomy (collaborative tagging).

• X-Drive - 5 gB storage free - allows sharing - requires AOL IM logon
• Orbitfiles - 6 gB storage free - allows sharing - movies, mp3s, any data
• Flickr - store and display photos - tag photos for sharing and join topical photo groups
• del.icio.us - store and share bookmarks - great for web collections - tag web pages

There are many more examples of this type of Web 2.0 application!
