You may be interested in a browser extension I launched at the end of last year. It keeps track of RSS feeds as you browse, helping you stay connected to the small web sites you discover.
I appreciate the observation, there's automated and manual curation that goes into this so there's definitely corpo stuff that shows up. We probably made things more difficult by wanting to include mainstream sources but heavily favor indie ones.
We have substantial lists of approved and denied domains so the authentic content is definitely there but it's not visible from a few clicks off of the categories page, we have more work to do.
