I suggest a public Villager Trading Post at spawn or something like that to where the staff runs it and the staff can choose on what the villagers want to trade and can have special offers. Anyone else?
As much as this would be cool, it could tarnish the economy, villagers can trade a large amount of items, also someone could ruin it by looking at the villager and AFK'ing not allowing others to look at its trades.
I started reading this and was let down by the fact that it didn't end in "but 'm sorry, but Beyoncé had one of the best videos of all time!
...a few years ago at an awards show, Kanye got up during Taylor swifts acceptance speech and started it with pretty much what you said. He followed it up with the Beyoncé statement. Also, feel free to drop by /v playershops on SMP1. Someone is running villagers there, or will be.
