I've been thinking about this for a while, and I've realized I've gotten a bit too deep into the "content consumer's Skinner box scroller mindset." I'm going to try to change how I approach this site, and maybe also other similar sites.
When I see an artwork I like, instead of just voting 5 stars and moving on as quickly as possible, I should take some time to really look at the image, appreciate the effort that went into it, try to come up with a comment, and take a look at the artist's page to see what else they've done.
