There are heaps of blog directories out there. Some better than others, and I guess it also depends on the theme of your site.
Known as the ‘Directory of Blog Directories’, Blog Skinny is relatively new compared to the other blog directories on the net, but is quickly gaining in popularity and number of links.
I like the layout – mainly because it is a little bit different to all the others, and I do get a bit of traffic referred from them 🙂 . I thought that that the traffic would die off after I first signed up and started getting the initial run of hits, but I regularly get traffic from them.
Your website gets rated by other ‘skinny’ users, and you can look at your stats in real time. Best thing is that it’s free!
