It appears that it's become very hard to do lately. I've been going over the blogs and it's really hard to find a blog that is NOT
rel="nofollow" or rel="external nofollow"
I tried web-sites like DoFollow Diver - The Premier DoFollow Blogs Search Engine (vast majority of the results are nofollow)
or free tools like comment Kahuna (not many blogs) or even lists which were assembled manually, but it's as if almost all of the blogs were affected by an update that made them nofollow.
Is there a good way of finding real dofollow blogs?
