There should be a large group of people outside of BitcoinTalk that are passionate enough and willing to provide enough liquidity to boot-strap the pool, no?
The large group of people outside of Bitcointalk who are interested in coinjoins are predominantly using Samourai/Sparrow/Whirlpool. As I've said 100 times already, even putting the whole mass surveillance thing to one side why would people abandon a better coinjoin implementation in order to bootstrap an inferior one which suffers from address reuse and deterministic links?
