I wasn’t 100% which was better, uservoice or somewhere here, API felt like the closest related section as it felt more devy to me.
The use case would be for websites that display lists of live users. While yes it’s possible to do an update every time the user goes live it isn’t really efficient in my opinion, and even with a system of looking up the id and it’s corresponding (potentially new) username once a day or every few hours, this will not tackle the issue if a particular user changes their username right before a new stream.
The user would be displayed as ‘online’ because the check was done via the id, while the link towards the user would be invalid as it still points to the old username.
It’s something that happened to me personally. I do daily checks to see if the usernames are accurate and had somebody change their username before a stream, on the live page that displays all users currently live this caused an issue in terms of displaying the videos preview as well as linking to the user. I do understand I could change my system to handle this but it’s one of my example use cases.
Another one would be on more static sites that don’t get too many updates or use embedded players.
