We have our spaces set up by the products we are developing, with separate spaces for non-product related functional departments. Within each product space, we branch pages off for development, product management, implementation teams, etc. It's very useful for us to have all these various teams in the same umbrella space for the product. However, multiple teams within the space would like to have a blog related to that product and we currently have the ability to create only a single blog for the whole space. I could move all of product management out into a separate space, but they're still going to want to create blogs per product or project. If I create a space for each team for each product or project, our space list will be enormous. Allowing multiple blogs, perhaps by a page branch, within the same space would make Confluence much more useful for us.
