So many web applications popping up from different companies, all using the web 2.0 tagging system - would be good to integrate them together e.g. for a rtm task you could see del.icio.us bookmarks, flickr photos or youtube videos with the same tags - a concrete specific example as to why this would be useful is if the task was difficult or you didn't know how to do it - these other sites might offer inspiration - for example youtube has many user-created tutorials.
