Do you see the gadget on the right sidebar where it says CHECK OUT THESE BLOGS? It's a neat little gadget that's been produced by The Daily Weblog.
Very simply, you go along to The Daily Weblog, submit the site(s) you want to be included, then click on Add to Blog in order to get the code to upload it onto your blog.
The gadget randomly displays the blogs that have been submitted on all the sites where it has been placed and generates traffic to your site. It won't bring floods of traffic, but in the few`days I've had it on my blogs, I've had more visitors from it than from several other schemes and directories that claim to generate traffic for you.
The image is nice and large, as you can see, and you can also click on the little button to the right to randomly go through other blogs.
Nice little idea! Kudos!
