Read/Write Web has an interesting post predicting that the killer application for RSS will be to track Topic/Tag/Remix Feeds rather than to track individual blogs or news sources.
‘One of the reasons I think this may eventuate is that blogging is and always will be a minority sport (as I’ve referred to it in the past). The killer app for RSS probably won’t be geared towards the current ranks of bloggers and geeks. When RSS hits it big, it’ll be because ‘normal’ people start using it – your Mom and Dad, Frank from Marketing, Jessie from Payroll, Dave from the local dairy. They won’t be bloggers. They won’t be interested in writing or podcasting or anything like that. All they’ll want to do is track news and trends that are relevant to them.
Tools will evolve to let people easily set-up personalized searches for information relevant to them and subscribe to the results – using, you guessed it, RSS! Google will probably be the front-runner (see this video for a hint to the future – thanks twdanny for the reminder), PubSub will be another, current players like Bloglines and Technorati will be in amongst it, and who knows who else.’
