Because the BlackBerry had no touchscreen, you navigated with a physical trackpad or the infamous ball. Scrolling through your jar was deliberate. To comment on a post, you hit the menu button, scrolled to “Comment,” typed with two thumbs on a physical QWERTY keyboard that clicked with each keystroke, then hit the trackpad again. Every interaction was a decision. You didn’t "like" mindlessly; you committed to the click.
Today, Facebook is a sprawling metropolis of ads, Reels, and algorithmic ghosts. It lives on supercomputers in our pockets that refresh 120 times per second.
It couldn’t do half of what the desktop site could. You couldn’t view events properly. Photos loaded line by line, like a 1990s dial-up modem. Groups were a mess. But none of that mattered. The jar was a portal. It was the first time "social media" felt mobile—not as a second-class experience, but as a specific experience. You weren’t trying to replicate your computer; you were checking in.
