There’s no wrong answer. They’re just different.
A platform is the home base for all your communication. It’s your website, your brand identity, and the products you make.
A program is the advertising that sells your tool using your brand, website, or personality.
Metaphorically: a platform is the TV channel, and the program is the commercial. Or you could think about television shows as the “platform,” and the commercials as the, uh, “programs” Programs exist to get you to notice a platform.
The sort of person who wakes up every day looking to make a program is different from the sort of person who makes platforms. It takes a different set of skills.
As for me, I like to make platforms. Which are you making?
