We will have pubic editing controls in version 4.0.
Permissions are based on roles. If your users belongs to the same role they will have the same permissions over blogs module. So you could create your own public editing control as described in the previous post or just add some granularity for the backend blogs, so that only the owner or author of a blog will be able to modify his/her blog and its posts. We will support granular permissions in version 4.0. Currently you need to override the behavior of BlogsListView and PostsListView to achieve some granularity .
