At Money Online, I found an interesting article about an auto fave program for Technorati. She says, "If you want to move up in Technorati there are 2 ways to get there: gaining massive amounts of links to you from other blogs, or getting the most favourites.
One way to do this is to add a lot of blogs to your "technorati favorites" and then hope that they (or ask them to) fav you in return. Obviously, if you do this, it's important to also return the favor. Here's a supercool autofave program from Eng Tech that does this automatically. If someone favorites you, they are automatically favorited in return.
Here's a diagram of how it works:
