Welcome to Treemo - Treemo: Media Sharing on a Mission: "Treemo is an online and mobile community dedicated to sharing digital media, empowering self-expression, and transforming creativity into action."
Treemo looks rather interesting - all content is mobile friendly, and they provide multiple ways of accessing content & uploading content via mobile devices without requiring a client application:
- Via Cell Phone Number
- Via Mobile Web Browser
- Via MMS
- Via email
- Or from PC online
Definitely worth checking out. They are also quite strict on content - copyright, etc...
