The author of Marginalia Search has left their office job to work on the project full-time, feeling a mix of relief and uncertainty about the future. They have a two-year runway thanks to a grant and savings, and hope to make the project sustainable through donations or commercial API access. The author is excited to focus on developing the search engine, which they believe has the potential to be a useful tool for navigating the web. They acknowledge that it's a gamble, but feel it's worth taking to pursue their vision.
