Congrats on launching; it's a big step that a lot of people shy away from. And congrats on the traction and comments you're getting!

I think there's nothing wrong with entering a crowded market or building an alternative to similar existing products - but I also think you need something to differentiate your offering! I'm not sure what that is for this product, but I think it's great that you launched and hopefully v the experience will help you design your next offering.
