The Collin Lahay blog have a great selection on how to get links from different places. One of the latest I checked was the Zillow links and it looks pretty easy to me. I took a second to see if I could find some other places where you can put links and I remember that I saw lots of links from the Pay Per Post form I had posted before.
But now is the question is that a good or bad link since Google pushed down Pay Per Post so much.
Give me your input if you have any links that you think do harm to your PageRank.
