I liked this article from Scott Belsky that talks about the importance of the first 15 seconds of interaction with new users. According to him, the keys are;

- Make using your product “share-worthy” so user look good when they talk about you,
- Deliver immediate benefit to reward the engagement to keep them hooked.
