I recently learned of BlogRush and wanted to see if anyone else out there was using it or had heard of it.  Here's more information straight from the source, www.BlogRush.com.

"BlogRush is a free service that was created to help bloggers solve their #1 need:
More Readers For Their Blog.

By adding the BlogRush Widget to a blog, a blogger can get instant distribution for their latest blog post titles across a network of related blogs.

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.

BlogRush is the brainchild of Internet entrepreneur, John Reese. Mr. Reese is the founder and CEO of Income.com, a soon to be launched social network and media company for entrepreneurs. BlogRush is the first Web property of the Income.com Network, a network of sites and services to help entrepreneurs and business owners succeed. Income.com is based in Orlando, Florida."
