I came across this interesting piece of social software last night while reading through a backlog of RSS feeds on NetNewswire.

Called Simuliciou.us , the site author describes it as:

… a mashup of del.icio.us and easyutil.com. It’s an experiment on my part to see whether I can quickly find relevant web sites based on people’s tags/bookmarks on del.icio.us, using the engine from easyutil.com. It answers the question “people who tagged this site also tagged what other sites”. I am using it mostly to find blogs that are similar to the ones I read, and to find new popular web sites that are in my area.

Although the interface leaves a lot to be desired at this stage, the functionality appears to be robust – I spent a while searching links to various sites that I visit frequently. I even tried the Mozilla/Firefiox bookmarklet created by Sjan Evardsson and now have it installed in my bookmark bar for ease of use.
