I think anon was referring to the long term threads that sometimes dominate here which often have a lot of effort put into it. Especially /go/ but sometimes sporadic other things like special events relating to /night/, rewatch thread and what not. So, it doesn't count as megaproject in that definition.

artfags, barely one that sort accounts, writefags, a handful in our history but activity is sporadic. I might check it out myself and if I feel inspired I'll contribute.
