Multiply is an innovative social network that allows you not to shahe only your images, but to share all you've got.

* post digital photos, videos and music
* publish your own blog
* schedule events and parties on your social calendar
* share movie or restaurant reviews

Standard feature is comments : Others can comment on whatever you post (share) on multiply, making it a discussion board as well. This certainly looks promising.

Multiply is not alone : Techcrunch recently reviewed Filemobile.
