Tracido: If it has new information, I'm sharing it.
I don't really care one way or another. (About opening a new thread for every new Youtube video on the internet, that is.) But you could do it in similar way as how those GOG and non-GOG game giveaway threads are doing.
Open one big thread and modify the opening comment to include the latest news whenever they come. That could be one solution. You could continue sharing interesting news. People who don't want to see a new thread about a single Youtube video are not annoyed. And those who are looking for these kind of news have one thread they can go to.
I see no downside. It's a win-win-win situation.
Protip: if you do open one megathread, be sure to be first to comment. That way you have the first two comments you can modify and add the Youtube links to. And that way the links won't get lost in between the comments.
