It would be nice to be able to assign permissions for a blog entry. There are some blog entries that are meant for your team and others that are meant for any user of the system. By extending the permissions being used in the wiki pages to the blog\news, you could allow for this multiuse of the blog section within a single space. You have to create 2 seperate spaces right now to perform the same feature and if a blog is meant for both audiences, then it has to be posted twice.
