[anti-censorship-team] Do we expect to have as many standalone Snowflake proxies as we do?

I was looking at https://snowflake-broker.torproject.net/debug just now, and saw:

current snowflakes available: 317 standalone proxies: 216 browser proxies: 0 webext proxies: 101 unknown proxies: 0 NAT Types available: restricted: 278 unrestricted: 2 unknown: 37

About 2/3 of proxies are standalone, which is more than I would have supposed. Has there been word getting out about how to run one, or something?
