What happened here? Can someone explain?

Is this a coincidence? On August 31 , I posted a discussion titled "leading man". Members were asked to name one actor or actress they would have loved to have as their leading man - or woman in a movie. One member mentioned Natalie Wood (pictured above) as one of his choices , and another member remarked that Natalie had died under suspicious circumstances. Her husband Robert Wagner was suspected of playing a part in her demise. Now here comes the part I am trying to understand. Most nights before going to bed I click on Youtube movies and select a movie to watch. Because of my initial choices, they know the kind of movies I am interested in - westerns, older type movies, the classics and historical movies. So every time I go there I would find a list of recommended movies of the kind I watch most often. Imagine my surprise a couple days after my post, one of the recommended movies was the 2004 TV movie - The Mystery of Natalie Wood. Suspicion about her death is mentioned in the comments section of my mylot post - and the movie about her life and death is recommended on the Youtube list. I should mention here that since I started watching Youtube movies I have never selected one starring either Natalie Wood or Robert Wagner. What do you think?
