BlogExplosion – can it really drive traffic?

I tried using BlogExplosion a few times last week and it did drive some traffic, although I would question the targeting, to my blog. I gave up though as it seemed to be too much hassle, and also because it kept presenting me with the same blogs over and over again that I didn’t want to see.

A post on AStepCloser, which seems a reputable blog has made me pause for thought. Is anyone else getting a lot of traffic from BlogExplosion or similar sites? Do any users introduced to your blog return of their own accord?
