It wasn't always like this. I used to have a reasonably cool feed centered towards technologies and news that are at least partly relevant to me and my industry. No more. It's all 'I gave a homeless person lunch and today they are the #1 duck breeder in Brazil' or some other nonsense.
I don't know when this started or if it is localized, but it renders the 'place to find useful information' aspect of social media completely void. There's no amount of reasonable curating effort that will save a news feed like that.
I try not to be too negative about things but without some serious change I'll use a static LinkedIn profile and visit it for a fraction of a second every week - to check for messages - and nothing more.
