Sometimes, an app really is just as good as it looks, and that's all there is to it. I like it better than Pocket, better than Instapaper, respects RSS, integrates email newsletters, even lets you convert your google/apple login to an email login with a click. Even support for a private library of PDFs and EPubs! I seem to be having a little bit of trouble adding highlights to Epubs, but this is just about the perfect app.

So now, it's just a question of when the other shoe drops and they look at monetization. How much will it cost, what will the free version lose, what data of mine will be sold, etc? As long as its good enough and stays true to what appears to be its current vision, I can't see why I wouldn't pay for it, so it's just a matter of trusting that it will stay good over time.
