Sandvox: Public Beta | Karelia Software
You should check out Sandvox, the website builder for the Mac that is coming soon from Karelia Software. It is in public beta now, so you can try it out even though it's not ready to buy yet.
(I'm encouraging people to sign up because it's a cool program, and because if you sign up, I'll get a discount when it's released. If you start referring people, you can get a discount too.)
