You're not just moving web dev in a better direction, but also fact and data based journalism and visualization! I first learned of Svelt and Rollup (and became your fan) when I asked how you made that great NYT article, The Follower Factory! I'm glad you've kept working on Svelt, and I can't wait to see what you do next.
