@Denny "My platform of choice for discovery and learning has been around for a bit, it's the internet." Me too. In the early 1990s Compuserve tried to pretend the Web didn't exist and that there was only Compuserve forums. But it was the only commercial Internet provider where I lived, so we had no choice. Ever since, I've looked at 'platforms' through that lens. It's all just corners of the Internet pretending to be the only game in town.
