Reddit, I get it
I've known about Reddit for a long time now, and I've browsed it on occasion but was always overwhelmed by the frequency of updates and sheer volume of content.  But just recently I figured it out:  Reddit's value lies in its user base.  The website is simple enough:  It's essentially a forum where users post things and other users comment.  One of the things that helps the community at large is the ability to upvote and downvote each and every comment, as well as the nested comments that make it more of a discussion.  But by far the most important aspect of Reddit is that its users tend to be a little more intelligent than the average internet citizen.  There are still childish comments and personal insults, but there's also deep insight and links to information that backs up opinions.  Instead of a typical web forum, Reddit is like a web forum of people you know, or at least people you'd like to know.  There's personal depth, sort of like real life.  It's really cool stuff, and I'm surprised it took me this long to figure it out.

Sports injury reporting language
Something I've noticed for a little while now is how injury reporting during and after sporting events uses strange language.  They say things like, "This person is out with a hamstring," or "Coaches say that person is dealing with a shoulder."  The "injury" part is implied, but it still sounds weird to me.
