Do you remember Google+? Flickr? Tumblr? Livejournal? Xanga? Facebook?
Moral of the story:
All external platforms will either eventually die or screw you over in one way or another. Thus the goal: OWN YOUR OWN PLATFORM!
Digital share cropping— you think you own the land, but you really don’t. Sneaky. I see the future as a new caste system. Rich people with no ads on top, poor people beladen with annoying ads and having to do manual labor (drive Uber, deliver food, etc).
