What can I build, parallel to building in public, which will amplify my journey and grant me exposure?

Think:
Dan Rowden's Ilo.so which is not solely his main product, but it reinforces his BiP journey with network effects and viral loops
Typefully, a tool made by Mailbrew's @Linuz90 and @Frankdilo. As Typefully (a side-product, when compared to Mailbrew) grows, the two gentlemen's story piggybacks as well.
Classic example: Basecamp launching their books, Ruby on Rails or countless other side-projects that reinforce their main story
 
My personal examples:
The Build in Public Cheatsheet I'm building (thanks for reading it!)
