izopodian philosophy: Sometimes a domain is just a domain, until you put it up on the world wide web. After that, it's all uphill. If you are able to find a domain that can "be something" without having to explain much, you will have solved half your marketing problems. If you think only dot com names have it easy, then you are woefully ill prepared for the future.
More izopodian philosophy: If you only think you can sell a certain domain, you will invariably end up with more domains than you could ever possibly sell.
