Marco Arment discusses why he created Instapaper:
“The goal of Instapaper is to facilitate the attentive reading of web content, as opposed to skimming. So many people read content by subscribing through feed readers with a thousand posts a day; it promotes the quick skim content instead of the deeper, thoughtful interpretation of the writing. ”
It’s about bringing back long-form content on the web — back from the drudge of empty posts consisting of lists, rather than valuable meaning.
