While I sometimes understand the bemoaning of top engineers spending time on trivial apps, sometimes those apps aren't as trivial as you would think when you consider how they positively impact loneliness. Of course, there's plenty of garbage out there, but I do love to see efforts to connect people in ways that can be serendipitous and have the possibility of leading to more meaningful connection.
I can think of multiple long-time valuable real-life relationships I've had where our first connections were on some trivial platform. Sometimes it's hard to see past the glaring negatives that come with some of those platforms, but I'm hopeful that better options will evolve over time.
