Back in its day it was good to use and I have had some good results using it, but that was when Google liked recip linking. It seems to have lost a lot of its loyal users and down 4500 to 9000 (ish) on the Alexa ranking system is a very sharp decrease in traffic. Concentrate your time now on building up one way links, automated link exchanges are a thing of the past, you just have to keep up with the times. Social Bookmarking, dir submission, articles, PR's, blog comments, etc are what you should concentrate on doing. If you search any link exchange service like linkmarket you will notice that a lot of them are losing lots of traffic and loyal customers, which tells its own story really. TD
