14th colony have a nice little list on how to choose a domain name. I disagree with number 4, in the UK use co.uk but aside form that its a great list
- Aim for obvious (like your company name or what you do).
- Keep in mind the role your domain name will have on your business brand and identity.
- .com is the best TLD. If you sell stuff commercially, people will expect your site to be a .com (www.yourdomain.com). And people type ".com" by default.
