Many have done what I'm trying to do but I will throw my hat in the ring.
I have a blogger blog that had limeted features but I got many hits from it, so now I am using portal software, I have my old blog linked along with other content like a forum(which is more interactive) user chat and wrapped links to keep users on my page while they surf.
Take a look here:
Exotica
I use joomla for the blog and linking part and smf for the forum, take a look:
Exotica forum
There are many programs with a blog bundled in, I use joomla but you can also use phpnuke.
And if you are one of those bloggers that can always ad content you can still have stuff to give your surfers something to do.
