A recommendation engine built-in to my read later service sounds great. But I worry that having yet another “inbox” to check alongside the services I already use — RSS, Twitter, and email — is simply going to be adding to the noise and not cutting through it.
What we need more of is features like Fever’s Hot section which displays the most frequently linked to web pages from the sites you’ve chosen to subscribe to over a specific time period. If I had a mechanism in all of my inboxes that surfaced the most interesting and important things for me, that didn’t require me to weed through the dregs, that would be something I’m interested in. For example, imagine if Instapaper could reorder your queue based on what you’re most likely to be interested in reading — it didn’t offer you new articles, just suggested a good place to start reading your existing ones.
