Thanks for the kind words! Singularity is still a core piece of infrastructure for running stateless apps at HubSpot (our status page currently reads ~13k Requests, ~22k Active Tasks, ~700 Agents). We're also heavily investing in Kubernetes, but Singularity is solid enough that our focus has been more towards reliably running and scaling stateful things like MySQL, ZK, Kafka, HBase, and ES.
