I'm convinced the initial randomness/anonymous feedback/chaos of that initial period helped grow the spark from the ember that split off of Infiniminer.
There is something creative in the chaos of 4chan - just look a greentexts. 99% of them are absolutely terrible. But the occasional gem catches on and made viral on the larger, less vile sites.
Also, I can't believe I forgot about Caturday. That started on 4chan as well. (also 10+ years ago).
