Here’s why I think this premise is wrong — and probably has the opposite effect of what you intend. Since what I save in Refind in public, it’s sharing. Not as explicit as sharing on Facebook or Twitter, but it’s sharing. And I share things that I like or consider useful, not just for myself, but hopefully others as well. Signal, not noise. Therefore, I read texts before I share then. Read Later (in Instapaper, in my case) is a triage for sharing. Saving an article on Refind to read soon (but share instantly in the process), only to discover the article wasn’t worth sharing in the first place, wouldn’t feel right.
