IMDb is shutting down its long-running, popular message boards after 16 years
Found on Polygon on Saturday, 04 February 2017
“Because IMDb's message boards continue to be utilized by a small but passionate community of IMDb users, we announced our decision to disable our message boards on February 3, 2017 but will leave them open for two additional weeks so that users will have ample time to archive any message board content they'd like to keep for personal use,” the statement reads.
So now you only provide services for a significant number of users and alienate loyal ones because the number shrunk? That's pretty harsh; and that's how you fuel the competition.
