Ed Dale says “This is the missing link!”
Go to www.posterous.com – it is a micro-blogging service. But, its best feature is that you can email in your posting! So you can take a photo with your smartphone, type in a few lines and send it to Posterous – and it is posted instantly!
Auto-post function – you can set up various blogs to receive your Posterous content. It keeps all the formatting, anchor text, links, media etc.
Facebook posting – Posterous will also post it direct to Facebook.
Tumblr – posts direct to Tumblr.
So, with one post from your iphone, it updates various blogs, posterous, Facebook and Tumblr.
Advanced Question – but what about the “duplicate content penalty”?? This is where Google does not display more than one version of the same copy in its results. BUT – Google still indexes the content AND it still counts for backlinks!!
