I use RSS Style[1] to make the RSS and Atom feeds for my blog human readable. It styles the xml feeds and inserts a message at the top about the feed being meant for news readers, not people. Thus technically making it "safe" for less tech savvy people.
I think it would. Having the ability to edit entries could prove useful under different situations. I see that it notifies you if you try to add a duplicate; That's pretty cool. I enjoy this project quite a bit, and it has sparked some interest in bookmark sharing in general. Thank you for this.
This is a nice clean app. Loving the simplicity.
Have you considered adding an edit function? It would help to fix links that no longer work or fix a typo, etc.
