I've got few subscriptions for an MVP I built in a less than a day!

I just built an MVP (https://www.preseedhere.com) in less than a day, 23 hours to be specific, and I already have few subscriptions!!! I literally did it just to prove myself that concept of building an MVP very quickly doesn’t make much sense, but I’m being proven wrong. Still not sure if this is gonna fly or not, but just wanted to share with everyone, it seems the concept is not super impractical.
