What treatment you want? Massage? Foot reflexology? Kidding..but seriosly what treatment u r looking for?
Frankly speaking none, from my experience. These users are uselss for adsense. they just totally ignore adsense ads. digg users are mostly advanced techies so they ignore Stumbleupon users are the quickest stumblers so if they spend more than 2 mins on your website, you should start distributing sweets.. Reddit---same as digg
For adsense, Bookmarking sites will not help. Most of the user will stay for 0 to 30 seconds and will leave. So, Traffic from social bookmarking sites are waste of bandwidth for which we are paying money. Brian
