1. Keep it short
2. Preference for .com
3. Forget hyphens and numbers
4. One syllable
5. A word you can say

A domain name does not buy you anything. Building a brand around any name is as good as any name, and still difficult. My reasoning is just buy 1 domain name and do everything there.

expireddomains.net is a great place to re-register 0 day deleted domains. People have decided not to renew the domain, and now it is back on the market.

My advice to IANA is to phase out all the domain name extensions except for .com .net and .org and limit a valid domain name to 12 characters max, at most along with no numbers or hyphens.

Here are some useless python scripts...
