If I have a domain name say
stackexchange.com and I want to host 2 sites X and Y as subdomains of that site.
x.stackexchange.com help out
y.stackexchange.com in page rank? Or will google treat them as 2 separate sites as far as page rank is concerned?
Is there any SEO benefit at all?
The question stems from this post and its answers and comments by the way: https://webapps.meta.stackexchange.com/questions/624/webapps-stackexchange-com-verus-nothingtoinstall-com
Comments like this one and others:
No doubt the site will be great either way. But all things being equal questions from a "smaller site" (with less traffic and less overall linkbacks as far as Google is concerned) will have a lower Google ranking than if the site is "seen" as part of a huge network (made up of all the SE sites combined) with ONE top-level domain.

Is it worth sacrificing the network effect of being on the Stack Exchange Network AND the lower Google ranking on every question (smaller sites will have lower rankings than a large network) to have the independent domain name? That's what I am asking. – Robert Cartaino♦ 2 days ago

@alexanderpas correct, and nothing will destroy that search ranking faster than splitting pagerank across 25+ unique domain names. – Jeff Atwood♦ yesterday
