Omnom is a self-hosted bookmarking service that integrates searchable, wysiwyg snapshots, originally created to fill the gap left by declining services like del.icio.us. After facing challenges with maintenance, it was revived by asciimoo, who rewrote it in Go, enhancing its functionality and stability. The service focuses on providing a privacy-respecting solution for personal and community bookmarking, making it accessible to those interested in libre software.
