This website makes me realize that I've been trained to "reward" others for posting online. I feel an uncontrollable urge to "upvote" or "like" comments but quickly realize the button isn't available.
Definitely a feature that it's missing
I like it, but I'm still adjusting! I can't tell if modern web apps have changed my nature though, or if it's "natural" to look for an additional level of interaction that isn't just words on a page.
