Trying new bloggin software for the Mac

Okay so this little program called MarsEdit


I am trying to figure out if this is any cool or worth working with. So far it is very text edit oriented but I kinda like the geek factor of that and actually showing code. Maybe it is the fact that I am working with code and blogging while waiting for pizza and watching Project Runway. If anything no one can call me non eccentric.

Anyone have any suggestions for great Mac blogging tools?
