If you had to choose between only reading Twitter or only reading weblogs,
which would you choose? Losing Twitter would be a bummer for a lot people, but losing weblogs would decimate the web. We should do more to strengthen weblogs and RSS because they are the foundation for so much of the most important writing on the web.
Joking aside, I do get a lot of my news from twitter these days. I would say half the articles that I'd be interested in reading (dumping to Instapaper from Reeder or Mr. reader) I've already added from twitter. Luckily, I use Feed Wrangler so I don't see duplicates of something already in Instapaper when browsing my feeds.
