Finding websites running WebSphere Portal

I used to wonder which websites or companies are using IBM WebSphere Portal Server. The easiest way to find them is to do a Google search on /wps/portal keyword which is nothing but the default context root or the base url for WebSphere Portal. I was surprised to see several websites ranging from government websites of different countries, banks, retail, telecom etc. The search should return all websites running websphere portal with default context root /wps/portal unless they have changed it using modify-servlet-path task which i believe atleast 80%-90% of installation wouldn't have done.
