Eric Siu explains why platforms and tools are different. Platforms like Facebook and Instagram get value from what users create and share. Tools like Mailchimp just do one job for you.
So the main thing that differentiates a platform from a tool is that the users provide most of the value. You're not just using it to like do a job, send emails to people like a Mailchimp, right? A platform would be something like Facebook or Instagram where you go there to interact with other people and their content that they're creating. That provides the value.
