Posterous Tries to Compete with Facebook/Social

Interesting.. I love Posterous for blogging, but they need to do more for managing my media (photo's at least) before they can compete with flickr and facebook for sharing.  Right now with Posterous, its really easy to upload photos.. but thats it.  No captioning.   Sharing photos across blogs posts isn't exactly convenient, etc.

.. and it seems that Posterous is pronounced paw-ster-us - like preposterous - not post-er-ous - like I "post" to my blog.
