Redstone is fun at the ground level, although once you learn more it will only create more an more headaches for yourself as you get more ambitious, trying new things - testing the boundaries. But in a casual sense, suitable redstone knowledge should be a staple for every minecrafter!

It is very fun. Go for it.

That sounds pretty cool! Why not give it a go?

Do whatever you feel like, everyone plays minecraft in his own way. I am into commands.

What do you mean? It's not much of a title, the correct question would be 'should I do redstone?'
