Phame Blogs (and maybe Posts?) should have a subscribers/CCs field. Use case would be maybe making an internal Engineering Blog and adding Engineering to the Subscribers. New Posts notifications would then be sent to everyone subscribing to that blog.
I use Phriction to write a weekly report which is shared around a large number of people. Currently, I copy the Phriction document into an email in order to distribute the report. It would be much better if I could somehow publish this report from within Phriction.
