I have found a couple more thanks to this site: http://www.momathome.com/.
There is Shadows, Simpy, Del.icio.us and BlinkList [although the latters site is not working]. Are there any more?[Via [C#, .Net Framework](http://feeds.feedburner.com/Kinlan?m=160)]I am looking for services that are similar to del.icio.us so that I can add them to my AJAX based DeliTag. I am thinking that I can upload the tags to Del.icio.us and other services in one go.
