Internal Links should not be "rel=nofollow" Says Google

Internal Links of a blog are those links which are actually pointed towards other pages or posts WITHIN your blog. Many people out there make this mistake, they add a NoFollow tag to their internal links as well. But actually those links are pointing towards somewhere within your blog and not external, why to use a NoFollow link. Matt Cutts (currently the head of Google's Webspam team) said that If you are linking one page of your site to another page on your site, Don't add rel="nofollow". So internal links shouldn't be NoFollow and its better for your blog's Pagerank to use a Dofollow tag to your Internal links.

Note: In case if you don't know the what are Dofollow and NoFollow links? then check my earlier post regarding Difference Between DoFollow and NoFollow links.
