> the rationalist community grew around publications by Eliezer Yudkowsky
Rationalism (in its current form) has been around since long before someone on the internet became famous for their epic-length Harry Potter fanfiction, and it will continue to exist long after LessWrong has become a domain parking page.
Sure, but currently we are discussing (inaccurate portrayals of) the community that grew starting in 2006 around Eliezer's writings. I regret that there is no better name for this community. (The community has tried to acquire a more descriptive name, but none have stuck.)
