Ok, I dont usually fall for these things, but this service looks pretty awesome. Its all over the blogosphere and hitting the social network forums etc. BlogRush is a new kind of referral network.Essentially, all you do is put a widget on your blog. The widget displays links to other blogs, but the cool thing is that it has context. BlogRush has an algorithm that works out the topic of your blog and displays relevant links in the widget. Its actually so useful and ive picked up really useful blog...
