I don't really like reading reddit anymore because I'm not convinced a large majority of the content is genuine. Reading anything in the news or anything political or even product recommendations just seems overly astroturfed and not genuine.
Facebook isn't really an option because Facebook still puts crap in your feed that has corporate interests, and people don't really friend strangers.
There is no "you might like this!" inserted into your feed. There are no ads. You get exactly what you subscribe to, and things that are "boosted" by the people you follow. It's starting to hit critical mass now with interesting things to read. Get involved.
I use Feedly on desktop, and as a back-end sync service for the many phone and tablet apps that integrate with it.
