It's pretty much impossible to get good rel=follow links nowadays. My startup has gotten some pretty good and genuine attention on blogs and forums, but almost every link appearing on the internet to my site is nofollow.
This is not how Pagerank was meant to work. Google has learned that it's core algorithm is failing to be able to fight spam. Nofollow was invented in 2005 and it will be useless in 2015, since the entire internet will consist of nofollow links.
