[Mac Sirloin]

Would it be possible to change the main page blog setup from descending from most recent to replacing the blog of an author still on the main page with a newer one? What I mean is:

MONDAY
Blog title/Author
BUTT by Opium Baby
FART by Jub Jub
ASS by Wankmeister
CLOWN by Asshole
STUPID by Sticky

And say Asshole decides to update his blog.
TUESDAY
Blog title/author
BUTT by Opium Baby
FART by Jub Jub
ASS by Wankmeister
CLOWN Part 2 by Asshole
STUPID by Sticky

And then someone not on the front page makes a blog...
WEDNESDAY
JESUS by Christfan666
BUTT by Opium Baby
FART by Jub Jub
ASS by Wankmeister
CLOWN Part 2 by Asshole

I ask as the person who probably pumps out the most of these things but finds it reprehensible to kick other blogs off the front page when I post more stupid shit that won't fit into a thread.

I'd have googled this but I'm not sure what kind of terms I could use.
