Welcome to the Q&A Forum

I know this has been discussed but was wondering what would be the best approach from an SEO perspective. I quite like the idea of setting up websites with domains without www but always worry that setting up domains without www has a disadvantage because user are use to referring to sites with the www included. Thus one of my fears are that users would link back using www version which will mean even if you do a 301 redirect that some of the link juice would be lost. I know some famous sites have used this convention such as http://searchenginewatch.com/ so think it would be possible but still concerned that for new sites it would be better to rather stick to conventions. What are your opinions about this?
