I hate to sound like the devil's advocate, but being a user of both sites, I don't feel like one is stealing the space from the other. Making claims such as "CA's forum will always live in the shadow of cr0" is perhaps dismissive of the fact that this community has been going since 2006, so I don't think comparing apples against pineapples will prove anything or do justice to one over the other (is bigger always better? the short answer is: It depends.)
I think what it comes down to is, some people here disliked CA and some people admired him. Those who disliked CA's style (at least, from my understanding as I didn't remember reading anything and can only assume the gist of it happened before I joined the forum, the style he conveyed during his last months as a moderator of cr0) will continue to support this community and the others who have no issues with CA will be able to join an emerging community with less attrition and a slightly stricter "indian cuisine only" (i.e no non-curry chat section, but no one frowns upon the occasional non-curry comment being thrown in) forum.
