Like I always say, I am new to blogging. Just today I came across BlogRush. Another new blog service launched by John Reese, a content syndication network that claims to be capable of sending free, targeted traffic to your blog. It is like show what's mine and I'll show what's yours kinda thing. You can see the widget at the left bottom part of my blog and you can see five feeds of different blogs.
However, I could not tell you how effective this is but you can try it out. No one knows BlogRush would be big someday.
For those who wants to try it register here.
