Here’s a shot of my BlogRush stats:

Let’s analyze the BlogRush widget, now about one year after its initial release.
Here’s what BlogRush claims:
“a free service that was created to help bloggers solve their #1 need: More Readers For Their Blog.”
This has proven true. I have gotten free traffic and more readers for my blog from BlogRush.
“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.”
This is true as well, but since the quality control is tight, your feeds don’t get syndicated across as many blogs as you would hope for. I applied with a few very good white hat blogs that the BlogRush team turned down. In their efforts to control quality for the syndication, they err on the side of refusing too many blogs instead of wasting their members’ credits syndicating on spam blogs.
“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.”
This is good, since you can build your syndication credits through the roof with a lot of referrals. This is a good alternative to trying to set up a spam blog to build you more credits. Play the game right, just get tons of referrals.
Overall, BlogRush is a good free option to content network advertising. Since it is free, it’s nowhere nearly as sophisticated as Google Adwords or anything like that, but it works and it’s free. It also makes you part of a “club” of respected bloggers since BlogRush’s quality control is so strict.
BlogRush gets an 8/10 from me, since good free tools are hard to find these days.
