I would like to see the ability to use the

{blog-posts} macro (or perhaps a new macro suited especially to this purpose) to display blog posts from multiple spaces.

Some examples of where this would be useful:

* Having a single page in confluence that displays all blog-posts happening across the organization
{blog-posts:spaces=@all}

* Aggregating several users' posts into a single display
{blog-posts:spaces=~msmith,~djohnson,~bbrown}

* Displaying all blog posts that have the label 'java' across all spaces.
{blog-posts:spaces=@all,labels=java}

* For backward compatibility, omitting the 'spaces' attribute would continue to pull in the blog posts from the space in which the macro is being used:
{blog-posts}

or, to be explicit:

{blog-posts:spaces=@self}

• Displaying all blog posts with the labels 'java' and/or 'orm' from each of the personal spaces of the members of the 'development-team' group: {blog-posts:groups=development-team|labels=java,orm}
