Switching from all "www' to no "www" seo

[londonhogfan]

I have a site that I setup to always be "www" if someone goes to example.com it will redirect them to www.example.com.

Now I regret this... My site has been up for a year now and a few thousand pages, but with the rise of twitter short urls are important and I would like to change me site to instead transfer everything to no "www" so everything will go to http://example.com.

I have a pretty good rank and it's not worth it to me to lose rank for this so my question is... will doing this hurt my rank?

Thanks for any help you can offer

I would expect that if the 301 is correctly done that ranking would transfer although you can't rule out temporary drops in traffic.
The 301's would have to stay in place forever as most of your incoming links would be pointing to "www" and the Page Rank would be lost without the re-directs.
Does Twitter justify the effort - especially with URL shortening now standard on twitter through the use of bit.ly

Just use a URL shortening service that utilizes 301 redirects. You'll still get the juice but you won't have to disrupt the momentum of your site by altering canonicalization.

Thanks for the advice.

I have setup shorter domain with the Google Short Urls app.

rev="canonical" may be useful.
