It seems that every new turn IMDB takes angers the users, so it would be great if IMDB could give an official answer on what they want and how they see users. Isn’t it what cookies are for? Normally, IMDB would be in a position to answer what the (hell) the average user does in IMDB. Does he visit it daily? Does he stay for 5min or 30 min? Does he watch a trailer and then leaves? Does he enter through his cell phone?
Around the 2000s I would spend much time in the message boards. Discussing a movie I just saw seemed the most normal and useful thing to do. IMDB owned a unique treasure of information and discussions in their message boards but they didn’t seem to know or appreciate it.
After the disappearance of message boards I became a... major list-maker. I know many people make crappy lists, the difference is that my lists (and some other people’s lists) were quality lists, they had good taste and huge knowledge and interest behind them, and thousands of visits, not because they were featured by IMDB, but because Google somehow realized their traffic and featured them properly. Now that IMDB deactivated commenting in lists, I guess most list-makers will gradually withdraw. Who knows? Maybe lists will suddenly be cancelled one day and we’ll get a message “Yes, we don’t support lists anymore. Sorry for the inconvenience”.
So, the question remains. What is there to do in IMDB if you’re not a pro and you’re not searching the filmography of an assistant electrician? Yes, you can review films and read reviews but more than a 100 reviews per film are totally unnecessary. How can one interact or exchange opinions in IMDB? Is there ANY such field left? Are you fundamentally against discussion and interaction or something?
