Looks great and a cool idea, feedback:

• I can't understand the video - it autoplays and there are no browser controls (firefox on macos), so by the time I finished reading the first few sentences on the page I couldn't catch up and I couldn't follow it at all
• I missed your get started button and Create Account button at the bottom, I did see the email box though so I assumed it was the app was unfinished and it was just an email collection page
• The suggestions are really cool! But you should ask some questions upfront to tailor them a bit more (e.g. I got one about Malaysia)
• In suggestions, clicking subscribe doesn't actually subscribe you - you have to click check and then you can subscribe
• When I click on a blog post, it should mark it as read somehow
• Would be great if I could drag items from a list into a new list (e.g. a "To read" list)

I don't use RSS feeds much so take my feedback with a pinch of salt 🙂
