I don't want to start a "my blogging software is better than yours"
thing here, but what are the alternatives to the big two?
As far as I can see neithyer has been updated since 2006. Why? is it
because they are fine as they are? They are great, but I'm surprised
that no one hasn't come up with something else just for the hell of
it.
I'm in the process of switching to radiant for my site. It has basic
blogging functionality and most everything else you'll need is
available in extensions.
The interesting thing about blogs is they are sort of a gateway drug for dynamic sites. I think you will likely find a decent amount of projects that include blog functionality, but may have some other larger purpose/slant. Radient, as mentioned, is one example.
I’m a developer on the Kete (Māori word for basket) project, found at http://kete.net.nz/ and itself an instance of Kete, and you can set up a basket homepage to present itself in a fairly blog like fashion.
So you might widen your net to see if there is a larger application that will suit.
