WordPress 3.1 RC4 for ObviousIdea.com

it’s a bit risky, but I have updated wordpress ( the CMS used to build obviousidea.com ) to 3.1 RC4
the site isn’t really in production so I don’t know so far about the bugs I will meet

a lot of changes everyday on the web site, and I m definitly not sure if using WordPress is the best idea. I have already reached my limit in using the template Versatile for WordPress, but the author is replying to my “dumb question”, let’s cross the fingers.
