How many ENS names are registered?

Could you elaborate on the current status of Ethereum Name Service (ENS) registrations? Specifically, how many unique ENS names have been successfully registered to date? This metric is crucial in gauging the adoption and popularity of the decentralized naming system. Does the number indicate a growing trend, or has it plateaued? Furthermore, are there any significant patterns or trends in the registration of these names that could provide insights into the usage and behavior of the ENS community? Any insights you can offer would be greatly appreciated.
