Make a feed of all blogs on one page

I have 3 blog pages with content in them. What I want is a feed that I can put on my home page that will show all the most recent content from all three blogs. Is that possible? 

As Justin posted, put three summary blocks on a page, each grabbing content from one particular blog. Set the blocks to filter featured content, set for one item each and when you create a new post in any of the blogs mark that post "featured" using the toggle and the summary block for that blog page will then update. 
 

Are there plans to update the summary component? TIA
