It can gather your content from popular webservices and publish them in one convenient place. For example I have created a SuprGlu page that takes the content I create from my weblog, from the Lewis Elementary page, from my various Flickr and del.icio.us accounts. The result is a chronologically organized web page of my various posts.
I was thinking this would be an interesting way to create a multi-author web site or aggregate classroom project site. For example I am teaching a class at Pacific University to pre-service teachers and we have been exploring the use of several web services tools including Flickr and del.icio.us. I plan to use SuprGlu to create a class composite page that collects all the content from the student created weblogs, flickr and del.icio.us accounts, and various other sites created and combine them into a master page that collects all the content created during the course.
