Wrong about what?
1. I did not say it is never useful to have keywords in a domain. I am not questioning the importance of keywords in domains. My domains appear usually in Top 3 SERP on Google, so I know how things work.
2. I said it is the domain buyer who decides about what is the reason he/she buys a domain. A number of people believe that certain domain characteristics are always important, but that is just their opinion. People buy things for their own reasons, not for Yours.
2. Web content can be Search Engine Optimized - Domains can't. Without a web page for it, a domain cannot be indexed in a search engine. Unless You see a dummy page from the registrar.
