Kind of weird name but I like it...
Performancing for Firefox | Performancing.com
I just read about this over on Om Malik on Broadband : » Performancing for Firefox, Awesome
I gotta say I think I love it. It's basic in some regards but it seems to have everything in the right place. It looks like it'll make blogging much more natural for me. We'll see. I like his recommendation of Ecto also. I've read about Ecto a number of times and I hope they have a Unibin version for OSX86 when I get the Mactel laptop.
Edit: manually formatted...it was bugging me.
