one other thing why www is good for SEO. shitty URL parsers. lets say you make a press release. there is a high chance that www.example.org gets automatically parsed into a clickable link (sometimes it's nofollow, sometime it isn't) - on the other side, there is a high chance that example.org does not get parsed into a clickable link, so you would have to write http://example.org to make sure that it get parsed into a link, which is just ugly - and - most of the PR stuff are reluctant to do.
some URL parsers have caught up to non-www domains if you have a .com domain, but try it with an .io domain. it fails most of the time.
that means there are some interesting hipness tradeoffs
* if you have a cool .io domain
* you should have an uncool www
on other thing about non www domains. journalists always get it wrong: whatever you do, whoever you pitch, as soon as you end up in a big and might print newspaper (that also has a website) you will see your domain with www again.
Does anyone who is not a startup founders think kitschy foreign ccTLD domain names are cool? They just confuse users. I am waiting for the day the new Libyan government desides they don't want American companies exploiting .ly. That will be interesting to watch.
