If everyone agrees that scheduling links help save time, then why are they so universally unloved? Today most booking pages present nothing more than a name and a calendar, so as the person receiving the link, the process of booking a time can feel cold and transactional.

The split is simple: Gitea for control and resilience, GitHub for reach. - Source: dev.to / 12 days ago
