User Blogs Question

hi there I got a question which I'm not quite sure how to word but let me give it a try.

FYI I'm trying to do this using the Social theme.

I want to offer user blogs to registered members I don't want them to spawn their own actual blogs. what I mean is that I want everything to display within the default Social theme. Much like the main blog does so that I have control over the layoutstyle and (preferably if possible)sidebar content.

basically I would like the user blogs let's say to display like Not talking about URL display on talking about the actual page.

so can this be done and if so any suggestions on how to do it.
