Sadly, part of the content issue is Facebook shooting itself in the foot because they refuse to show a simple chronological list of what people have been up to. They literally already have lots of content that would be interesting and they refuse to show it, instead opting for these weird algorithmic “views” that won’t even stay consistent between the time I follow a link and go back to the previous page. No wonder I quickly lose what little interest I had.
I would love if social networks were banned from search results too. I am tired of Googling things on “the Internet” and finding lots of results that are essentially “we showed this entire page to Google but all you get is a log-in page”. If your site is displayed in search results, you should be required to have at least a paragraph or two “always on” so that I see something when I click the link, instead of absolutely no content and a log-in/create-account page. If you want to hide 100% of your content, make your own damned search engine.
