A "news" site that focuses on providing only funny content and positive factual information related to the ongoing massive problems/disasters such as wars, pandemics, natural disasters, etc. There could be different versions of the site for both global and local news.
Reading news about massive disasters is depressive and while it's important to stay informed it's easy to slip into a downward spiral of negative thinking especially if the problem is long ongoing and you keep reading the same saddening news every day.
Reading something positive/funny related to the problem pushes you out of the negative mindset and helps to balance your emotions which in turn brings more positivity to the surroundings through social interactions and might bring the motivation for people to constructively deal with the problem rather than just crying about it.
Even though you can stumble on such positive/funny info from time to time on social media or elsewhere on the internet, it is rather scattered and there's no one specific place you could go to, to have a dose of positive emotions regarding that particular topic.
It would work in a similar way that social media platforms work. You'd register and create a profile. Then there would be separate channels dedicated to posting/reading information on separate topics. You'd link memes, bits of positive information from sources scattered all over the internet and post it to that channel. You could compose your own memes, post insights, etc.
There should be moderators checking every post to make sure users don't provide disinformation or post something obviously depressive. This is not to say that this should be a "sunshine lollipops and rainbows" feed, the posts could be proposals for constructive solutions, calls for action, reports of something positive that happened in the midst of the catastrophe, irony, self-cringe, etc.
The moderators should make sure that all the factual information posted (if it's not an obvious joke, meme, etc.) is legit and not based on opinions, wishful thinking, etc. Professionals in the fields that are relevant to the problem (journalists, politicians, scientists, etc.) could be responsible for maintaining the "positive news" part of the feed, there could be separate sections for positive factual information (news) and everything else (memes, jokes, insights, etc.).
The line between positive and negative (or even neutral) is subjective and there's no easy way of grouping the information into good and bad, and I'm not sure how to deal with this problem except from relying on opinions of the moderators. Any ideas?
