I am always aware that RSS is still a bit arcane for your average web user and I do believe that more intuitive, user friendly ways of finding the good stuff need to be constantly sought after. Steve Gilmor kicked off a bit of a fuss recently by claiming that RSS was dead and that we now use Twitter to find things. I believe he overstated his case deliberately to trigger the firestorm that ensued but I do know what he means.
In terms of keeping across things that might be interesting but that don't fall into my own horizon, I use a combination of Twitter and various other tools, synthesised in Friendfeed to help me scan what is out there and find the good stuff. However RSS is such a core part of the plumbing of the web, enabling content to migrate and flow far beyond the control of the originating sites that claiming it is dead is nonsense.
