Website names tell it all

When I see people purchase domain names that are long, I always cringe, the idea is to have a domain name that gives a hint to what the site is about or at least one that will be easy for people to remember. A recent example is www.acnesolution.org, it's fairly easy to determine what the purpose of the website is, it focuses on solutions for acne. That makes it easy for consumers/shoppers to remember and also helps when it comes to keyword search engines.
