IMHO... blog comments, even on VERY relevant blogs, are only worth a penny or two at most in backlink value, nofollowed or not!
Let me throw a "but what if..." at you here.
But what if those blog comments were on a moderated blog of PR6 / PR7 and the blog owner only allowed a select few comments in the first place (maybe 3 or 4 per post) and none of them were of the traditional spam variety.
Any benefit there?
