Personally, I don’t like the idea of any recommendation or advertising algorithm using personal information of any kind. Though I can understand why location would be needed for advertising: in order to ensure ads for regional services are not shown outside of that region.
The kinds of data that I think should be used:
-Recommendations:
-Like history
-Watch (or view) history - specifically (and only) if I click on a post or watch more than some reasonable percentage of a video that would indicate I watched the entirety of the video.
-Advertisements:
-Location (based solely on IP)
-The content currently being viewed, based on a general categorization of the content. If I’m watching a video about technology I don’t need to be seeing ads for financial services.
There have been several shows that I’ve watched on CR that have been made a lot better by being able to read the comments section. Either because it’s One Piece and there’s always one guy giving you the timestamp to skip the recap or because the series I’m watching is actually pretty bad and a bunch of people are making jokes at the shows expense.
It’s been rare that I’ve seen someone on CR be overly negative or toxic without getting shutdown fast. It’s usually pretty wholesome and fun.
