I didn't start with working group count, I was just responding. Current working groups aren't what you really want, since it's future work, and lots of AD time isn't on working group management, but if you want to know "how much does the workload of TSV compare to the workload of RAI", one measure to approximate relative workload is the count of working groups. More significantly, it's not like we're done with web and security, or web and privacy or web and payments or ... The work lacks focus. "Origin" left websec, moved to WHATWG, but it's back now in URL. I'm imagining the workload of WEB ADs would include more liaison. Larry
