Sites and apps where people share posts, photos and videos and follow each other, such as [LinkedIn](https://ecosystem.samcarlton.com/linkedin), [YouTube](https://ecosystem.samcarlton.com/youtube) and [Facebook](https://ecosystem.samcarlton.com/meta). Startups use them to find customers, hire and build a following.
