I was immediately disappointed by hello. The pre-defined interests are limiting and the presentation is nothing more than an instagram feed. Over a period of days, people were adding me as connections, and I had no idea why. None of it made any sense. When I log into the app, all I saw was random content completely unrelated to any interest at all.
This isn't about connecting based on interests. It's about being bored and needing instant gratification from notifications.
