It's true that walled gardens have been eating up useful information and that is a real shame, but make no mistake: there's still a ridiculous amount of good stuff on the open web. They're not playing the SEO optimization game so they get buried.
I have sort of got stuck in this bubble of reddit and not much else and... the way people behave has really sapped my desire to contribute anything to the world. I'm looking around me at the opinions a lot of people are expressing and I think... no, these people don't deserve nice things. It seems sometimes like the whole world is full of venal, bitter and divisive people that do nothing but snap bitterly at the heels of anyone that makes something of themselves or strays too far from safe consensus.
Do you think there's a lot of good content out there left to index?
