That's a pretty ignorant statement. Domain names can go a long way towards achieving great search rankings, which is why the better .net and .org domains sell for 10's of thousands of dollars. Though, I would agree that for those types of meaningless web 2.0 names you better get the .com, since all the marketing you do to build your brand will be pushing lot of direct traffic to someone else's domain.

that's what i meant. .orgs and .nets surely are worth a lot for the SEO potential thanks to the weight search engines place on domain text.
