"Problematically, RSS is still not quite a household word yet, and even the software industry is just beginning to realize the importance of this workhorse syndication format. Though at this point it's already clear RSS will be the key enabler of Web 2.0 and Software As a Service. It will do this both as a notification system and as the actual glue that will eventually hold many Web 2.0 services and mash-ups together."
