I think you should increase the focus on being multi-device. You're competing (I think) with Evernote and Pocket for example, both have outstanding cross-platform capabilities.
This looks fantastic when I want to save something from my laptop browser, but increasingly I find myself saving from a mobile. This is fine for Pocket or Evernote, I just share it to their app, but that's not an option here. I'm also not convinced from your landing page that I can have a satisfactory reading experience on mobile, you don't show that at all. You say I can access the data - but assuming you do have a good mobile reading view, you should show that.
It's a bit different then this :) We will integrate with Evernote and Pocket so everything from desktop will go to those apps were you said already have a great reading experience.
We have strong mobile strategy, but at the moment focusing to "nail" the desktop experience.
That's awesome! 2 way sync with Pocket would be amazing, this is a much better reading experience on desktop and I can use Pocket for now if necessary on mobile. You'd also get the awesome IFTTT ecosystem Pocket is in if you're not going to be able to match that for a while, saving from Feedly to Pocket is awesome and it'd be great to get saved RSS in Dragdis too!
I was just about to edit in that I really like your focus on pictures, that's where what I currently use falls down badly. I can definitely imagine I'd save more images using this.
In terms of your desktop experience, would you consider one click (not drag) page saving? In your video it looks really tedious dragging from the URL bar to a sidebar on the right when you could just have a button to save in one click and categorise later.
