I fear that the humor in it, much as I like humor, is a mistake. First, it comes across as a gender troll. Any technical attention the tool receives will be smothered by that avalanche. (Exhibit A: this thread.) More importantly, it impedes how the tool needs to work: get to the point immediately and cut everything else. Man pages may be Byzantine, but they do this well.
If I need examples for curl, examples for curl are all I want to see. They should be laid out readably and minimally (a nontrivial design problem). The last thing I want is a joke repeated everywhere. I'd say the same about the upvoting and downvoting stuff that appears in there: it's extraneous and distracting.
When I'm stuck on a shell command, it's usually because I have a specific task I'm trying to do. All I want is for the light bulb in my head to switch on so I can go "Oh I get it!" and go off to do the task. The best way is to see an example that's close enough to what I'm trying to do that it's like a magnet that attracts my specific task and snaps it in place. That's why I like the idea of this tool. It should focus on getting the user to that moment as quickly as possible.
It's a sorting mechanism. This is basically like Urban Dictionary but for Unix.
But yeah, it would be nice to hide the instructions after every single entry.
If it works, it will be useful.
