Ask HN: Interested in learning k8s and willing to beta test our platform?

We're building a new hands-on kubernetes learning platform and it'd be great if somebody interested in learning k8s would like to try us out. Maybe some of you remember us, we had a Show HN months ago as Magic Sandbox and since then we've been building on the concept. We're still rough around the edges, but we're happy with how things are shaping up and we'd really apprecate some feedback. If you're interested, have a look at the short tech demo video: https://www.youtube.com/watch?v=SkjMUY_cAmw and let me know to get a signup link (or sign up at msb.com)
