Parler is gaining popularity with people who want to use social media primarily or exclusively to talk politics.

This is not a large enough user base to generate useful network effects like with Twitter and Facebook.

Remember: politics is downstream of culture.

The interesting problem, however, is that people want better experiences for discussing politics on social media (sometimes just occasionally).

This is where entrepreneurs should focus.

Long-term, social media will become a standard like HTML or email.

This means users can choose the parts of the Parler experience they like (e.g. no censorship) while still benefiting from network effects (e.g. being able to share with everyone).
