Just came across BlogRush which happens to be a blog syndication network. Blogrush requires a user to register for the program. A widget ( see figure below) is then given to the user which can be pasted on a particular blog.
As per the Blogrush website “BlogRush users earn “syndication credits” (the right to have their blog post titles shown inside a widget on another related blog) based on their own traffic (loads of the widget) as well as the traffic of other users they refer to BlogRush. Users can automatically refer others to BlogRush via special links on the widget, as well as through the promotion of a special referral URL they are given.BlogRush is a “Cooperative Syndication Network” that rewards its users for their contributions to the network — from the impressions they provide of the BlogRush Widget to the referral of other users through 10 ‘generations’ of activity and the impressions of the widget that they provide. BlogRush was designed to be incredibly viral and to provide its users with tremendous distribution leverage to receive exposure for their blog content (onto related content blogs) that they could never achieve on their own; at least without a massive advertising budget. ”
P.S: I havent still used Blogrush, however, i have heard some good reviews from a couple of bloggers i often interact with.
