IMDb's message boards were supposed to encourage discussion among movie buffs, but that's not how they've turned out. If anything, they've developed a reputation for haters and trolls -- you'll even find naysayers ragging on people who like Casablanca and Citizen Kane. And apparently, IMDb has had enough. The Amazon-owned database is shutting down the boards on February 20th after determining that they're "no longer providing a positive, useful experience" for most users. Data and traffic helped influence the decision, IMDb adds, suggesting that they weren't popular enough to warrant keeping around.
