Netflix does this annoying thing where "Continue watching", "My list", "Trending now", and "Watch it again" appear in randomly different orders each time you log in. It would be like if Word randomly put the File menu on the right sometimes.
Lies, damn lies, and statistics—whenever a company relies too much on data to influences UX or content I feel like we end up with a bad UX and bad content that only superficially increases short-term engagement.
Sorry, but now you have a list of trending stuff, look at all this good stuff!
You want to watch some, right? Do it now or later, no pressure!
It also helps retain people who would otherwise leave in some cases.
