WPMU "Blog" in URL for Posts

Looking to find out a way to not have the word “blog”show up in a Post URL on a WPMU installation such as this http://thinktaiwan.com/blog/2012/01/25/mj116-just-believe/

Is there a way to remove the word blog? or change it to say something else? I will be creating a multi-site installation that only allows user accounts to be created not sites. I am doing this to take advantage of several super plug ins that are only compatible with Multisite. But I don’t want the word “blog” showing up in the site’s URL as it won’t be branded that way. Hope that makes sense. Thanks
