I tried traffic swarm and I didn't like it at all. I think it might work better on some sites than on others, kind of like adsense works better on some sites than others. I also thought it extremely annoying to find websites I had no interest in on my homepage everytime I opened up my browser. Maybe, though, with Firefox, you could have a number of tabs that open with your browser and maybe keep the Traffic Swarm on a tab that is under another. Of course you have to click on the sites to get credits so you'd have to look at it at some point. The biggest problem with it is that people are clicking on your site just to get the credit, not because they are truly interested. Not a very valuable click. I like signature posting better. That way you get a valuable click because the clicker already respects you and *wants* to visit your site to see what else you have going on. Much better traffic.
