I came across a nice piece of free software and I posted about it on my What A Load Of Bullshit blog. This program will allow you to get quality backlinks to your blog. Apart from increasing traffic it should also hopefully facilitate a higher PR ranking. It works by separating the blogs that do use the 'no-follow' from the ones that do not. It also allows you to target keywords PR rankings and different blogging platforms including Squidoo. I can see it saving the serious blogger a whole heap of time.
