I love APIs. And I have a particular affinity for using APIs within Sharendipity applications. Garry, Sachin, and the fine team here at Posterous have a great API for posting and reading from your Posterous.
I took advantage of the reading API by creating an embeddable widget that streams my Posterous photos.
Would you like to create your own embeddable Posterous widget? You can use this Sharendipity wizard to personalize the stream for your own Posterous and take your Posterous media anywhere on the web!
