A new service called BlogRush has launched, which promises to drive traffic to your blog. The service requires installing javascript code that loads a widget on your site. BlogRush is supposed to be able to cull links to relevant posts from other participating blogs through some kind of contextual page analysis. As described on their website, the service sounds a bit like a pyramid scheme, in the sense that participating sites will be listed on the widget based not only on your own site visits but on those of others who sign up based on your referrals. I’m not sure how much I’m going to like seeing this widget spreading all over the internet.
