It all depends on what the site is going to be used for. I like for my domain names to be indicative of what the site's purpose is. I don't recycle my domain names. If I choose to take my web in a whole new direction unrelated to it's original purpose, then I will create a new domain name to do it. The criteria I use to come up with a domain name: 1. Purpose of website; 2. Relatively short name; 3. Easy to say; 4. Easy to remember. I also don't host with companies that add their domain name as a prefix to my own.

"It is good to see ourselves as others see us. Try as we may, we are never
able to know ourselves fully as we are, especially the evil side of us.
This we can do only if we are not angry with our critics but will take in good
heart whatever they might have to say." - Ghandi
