This question already has an answer here:

Someone post a comment on this question saying that a reason of having many questions about facebook could be because http://facebook.stackoverflow exists

I tried to visit php.stackoverflow.com and perl.stackoverflow.com and they don't exist.

Why facebook.stackoverflow.com and no other ?
What is the main purpose of having facebook.stackoverflow.com ?

The purpose is to invite bad questions from misguided users on other people's sites. – Anthony Pegram Jun 11 '13 at 18:35
Facebook Stackoverflow? – Juhana Jun 11 '13 at 18:35
It was done to get facebook to pay stackexchange some money, not because it's useful. – CodesInChaos Jun 11 '13 at 18:37
@BradLarson Thanks. It's more than only filter tag. You see only reputation gain with the facebook tag. – Luc M Jun 11 '13 at 18:40
@LucM No, it shows all rep – CodesInChaos Jun 11 '13 at 18:42
@CodesInChaos From the link... "We can now create a mini-site by selecting relevant tags (in this case, anything Facebook related) and grouping together just the content from those tags. When you visit a mini-site, you’ll see only the content from those tags." I didn't verify the rep of Jon Skeet. – Luc M Jun 11 '13 at 18:45
@LucM Reputation != content. – J. Steen Jun 11 '13 at 18:50
@J.Steen Then, I don't understand But you're right, content != reputation :-) – Luc M Jun 11 '13 at 19:18
@LucM What is it you don't understand? That view is filtered per time period, which is selectable up to the right. =) – J. Steen Jun 11 '13 at 19:51
@J.Steen Why Jon Skeet is not on that page ? Check my link. it's for all time... – Luc M Jun 11 '13 at 23:48
@LucM That particular page is sorted by (I'm assuming) most reputation earned in the tag. It doesn't exclude other users. =) – J. Steen Jun 12 '13 at 7:12

They launched that a couple of years ago when Stack Overflow became the official developer support channel for all Facebook developers. The filtered view of Stack Overflow was designed to make it easier for Facebook application developers to see only content from relevant tags.
