Imagine a newspaper that got more and more clogged with old stuff every day, as every category of news accumulated all the old stories you didn’t read, and showed them to you every time you looked, as if this time you might actually want to read a story that you didn’t want to read the last 80 times you looked.
Your daily newspaper doesn’t tell you that you haven’t read 83,284 articles, why should your computer-based news tool?
Well, that’s how most feed readers work, and it’s just plain wrong. Your software should, instead, find the new stuff since the last time you looked and show you that first.
