It seems that sometimes the smaller hits back from sites turn out to be the most productive. Maybe it's more refined versus a quantity hit amount. The hubby learned way back in the mid 90's to never ignore any source of traffic. Especially the small ones. He says he'd rather have 50 focused or refined hits than 100k of non.
Use the high quantity to hopefully pick out some good bookmarkers that may eventually like some content you show and sign up. Its sort of like tgp hits. Just because someone can send you 1k-100k doesn't mean the traffic is worth a darn. It just pays to take every hit you can get. Thats why we never use script trading. We add a site to our list and let the surfer decide if he likes a sites name. If it turns out we end up losing all the traffic then it means we are doing something wrong with the site and need a revamp or some such thing.
