Matt Cutts said that they reserve the right to treat them differently and give the links in paragraph more weight. Which makes sense, if they can get it right.
But it also makes sense that one will have many more blogroll /sitewide links than one articles /blog posts written about them. Great site equals many mentions in articles but also many listings under "Useful Sites" type links.
