I am trying out this post aggregator called Posterous. It allows you to use email for posting to many other sites where you post content, like Flickr, Facebook, Twitter, etc. It has a neat idea of specific email addresses like firstname.lastname@example.org for posting to facebook and likewise for others. You can even combine destinations, like email@example.com. For links to images, it inserts the image for you (I think), for videos, it embeds the video player in your posts(they say).
