RSS feed...

Hmm... what is RSS feed? How will it affects my Internet life? Right now I am spending quite a lot of time browsing on many sites which some of them seldom update. Is RSS gonna save me my time? Hopefully, I can get an answer to this thing...

Right now, 60% of my time is online (unless I am on the road). I need some guidance on how to improve my quality net life. At least, I don't wish to spend majority of my life being a netslave... :'(
