What is the difference between facebook.stackoverflow.com and stackoverflow.com aside from the subdomain and the other title?

Both pages are using the same questions and the same user profiles/information.

On facebook.stackoverflow.com I can also see my questions not related to facebook: http://facebook.stackoverflow.com/questions/12567518/how-to-handle-dynamically-loaded-managed-libraries-in-c-sharp

When I set my favorite tags to some facebook tags and nothing else then is the only difference the title, the icon and the subdomain, or are there notable special features on facebook.stackoverflow.com?

  • Have you read the FAQ? It's basically a filtered view of SO focusing on Facebook-related tags only. Oct 17, 2012 at 13:05
  • in the review queue, there are questions tagged facebook with comments saying "this is offtopic: ask on facebook.stackoverflow.com" - are those comments just wrong? Oct 17, 2012 at 13:12
  • afaik it is possible to ask facebook related questions on stackoverflow and it is also possible to ask facebook unrelated questions on facebook.stackoverflow

    @KateGregory: yes, I'm pretty sure they are wrong. Oct 17, 2012 at 13:16
  • You can read all about it in this blog post: blog.stackoverflow.com/2011/08/facebook-stackoverflow Oct 17, 2012 at 13:20
  • @Paedow true, but on that "sub domain" there are added tweaks and tricks like taking your Facebook profile picture. Oct 17, 2012 at 13:22
  • And the other side's blog - developers.facebook.com/blog/post/545

    @Lix cool, wasn't aware that Stack Overflow replaced Facebook's forums which are now nothing more than spam container... :) Oct 17, 2012 at 13:23
  • @ShaWizDowArd when i first registered on stackoverflow (approx. 2 months ago) my profile picture automatically synched with my facebook photo, so that´s not only on facebook.SO but the blog entry is very interesting and the entry from facebook itself complains it.

  • @Paedow yeah, that's because you were using your Facebook account. Anyway, there are benefits in that site see the blog post.. Oct 17, 2012 at 13:26
  • ok, but really now there isn´t any difference xecept of the different settings and some visual stuff

The FSO filter only displays questions containing one of the Facebook related tags.

  • but this is only on the first page
