I would definitely use this, and probably (depending on just how much it improved my life) pay to use it.
One tip, to solve the "chicken and egg" problem of getting a good garden going while still consuming current levels of information, allow the user to choose to include some of those "low quality" sources as well.
For example, right now the vast majority of my info comes from HN and Reddit, both from links and comments. Ideally I'd be able to subscribe the service and keep getting all that info, then as I slowly build up my own more personalized, curated sources I could slowly start to remove the low-quality sources. I think if you could make this a pretty frictionless process you'd have a winner.
