I've got a client that likes the format of the silverstripe blog. In lieu of bringing the bulk of their social media into the blog format, which i have previously inquired about, has anyone fashioned/found anything that would push a silverstripe blog post to external social media blogs. (ie. silverstripe > facebook/twitter/tumblr/google+/blogger?? There is a loyal following to their external blogs that they would rather not have to create an exodus to the next blog, but instead do it gradually.

i would look into an rss publishing service. Some social networks even have rss --> post built in.
