I delegated 40 SP two days ago and plan to increase it to 100 SP.

The quoted part is something I never thought about but it is a nice idea actually.

Imagine world where upvotes could be used for anything. Visit a museum, but instead of paying one expensive ticket, you could just upvote paintings that you actually want to see. Or just pay for coca cola from ATM with your upvote or pay for some cool artwork from another Steemian at Steemfest!
