Techies on the other hand will migrate to other products, and RSS will keep chugging along as a techie-only protocol.
It's not that Reader or RSS have no potential value to anyone who isn't "good with computers." It's that Google never bothered to tell anyone it existed! And why should they? Modern Google doesn't give a shit about the open web or decentralized culture, they want to "own social" and keep everything contained within their cancerous Facebook clone.
A lot of people just didn't know you could have a service like Google Reader.
Following any more than a couple sites without this type of service, where you have to bookmark and visit the sites daily or periodically, makes it feel like you're changing channels on a TV without a TV guide view. Which is one reason why sites like this and reddit are so prominent.
