As someone who works extensively with marketing teams, often times - content is available but has not been formatted appropriately for the medium. Like a newsletter cannot work in the same way as a blog post which cannot work for SEO driven articles. Is there interest at HN for a Heroku for content where you could build foundational sentences, express your intent and we can figure out the right medium and the right message?
2 Things worth come to mind.<p>1. Digital Asset Management Software - I am sure you are familiar with them, but large companies use these to be able to leverage past projects for future projects. e.g. if you bought an image outright, being able to use it on something else.<p>2. Approved Content - Large organizations have specific words or style they use and want to be consistent across the board. The system you are describing one could do this. Have you seen <a href="http://www.teamsli.de" rel="nofollow">http://www.teamsli.de</a> ?<p>Good Luck!
Sounds interesting to me! I write newsletters, blog posts, social media content, and more. Starting from a foundation/ frameworks would help save tons of time. Do you have any kind of prototype yet?
