Back in 2007 I built a social RSS reader called Feed Each Other (
http://feedeachother.com). It was actually pretty good, but I had to give up on it because I ran out of money, Google Reader was slowly stealing all my features, and I found it very hard to convince people to switch from GR.
It had stuff like:
- "Circles" aka, letting you group your contacts however you like and see what each group shared with you and share stuff with all your contacts or just certain groups.
- Feed and user discovery and recommendations. "People who read X also read:" and "Look who subscribes to this feed" type of thing.
- Keyboard shortcuts, auto discovery, opml import/export etc. All the usual feed reader stuff.
Check out this old intro video I made for it (social/interesting parts start around 1:40). The design in the video is out-dated though, it ended up looking like this, http://feedeachother.com/screenshot_500.png. http://www.youtube.com/watch?v=h1Ltwh4AO_w&feature=youtu...
Maybe I should turn it back on? Any takers?
