Microsoft Clarity: pros & cons

- Basic Surveys: Lacks the deep user feedback and survey tools found in Hotjar.
- Reporting Limits: Analytical filters are powerful but less customizable than pro tools.

Substack: pros & cons
- Zero Upfront Cost: No fixed fees regardless of subscriber count (takes a 10% cut).
- Data Ownership: You own your subscriber list and can move it elsewhere anytime.
- Organic Growth: Its internal recommendation network helps you find new readers.
- Simplicity: Focus strictly on writing without worrying about design or tech details.
- Personalization: Your site's design is nearly identical to thousands of other Substack pages.
- Commission: High-earning writers may find the 10% cut more expensive than Ghost.
