Step 1 for a category defining product will never be the same as step 1 for a future competitor to that product. What worked for GitHub as step 1 will never work as step 1 for any service that replaces GitHub, because GitHub’s very existence changes the environment that allowed their step 1 to enable step 2. This is the luxury of first-mover advantage. GitHub only had to implement “good enough” features to attract a community. Any competitor that usurps GitHub will not only need to implement the right features, but also figure out how to move the community from GitHub to the new platform.
