I want to ask question about problems in my Facebook account. On which Stack Exchange site should I ask?
Questions about using Facebook are on-topic for Web Applications SE:
Web Applications Stack Exchange is for expert and advanced users of web applications.
If your question generally covers …
- Using Gmail, Facebook, Twitter, Google, or any other website which behaves like an application
Do study the site help center to see what is on and off-topic.
If you have a Facebook support issue, you'll need to contact Facebook directly. Web Applications SE can help you make sense of the features Facebook offers (e.g. how do I prevent my photos from being seen by anyone but my friends?), they cannot fix broken accounts.
Well, my first idea was the http://superuser.com, which is a very friendly site with a surprisingly wide topic. But, as @AI.E. and @psubsee2003 explained in comments, the questions about web apps are explicitly offtopic there. Thus, only web-apps remains.
The main problem of the FB questions, which can lead to similar offtopic decision, is probably their tendency to have a below-average quality.
Thus, anywhere you ask, make a high quality question:
- Formulate well, in clear sentences
- Give an interesting title, in a clear question: don't forget, answerers see 50 questions in a column and it is up to them, where they click
- Use screenshots to make your problem clear, but don't make too big and too many (extend the imgur link with an "m" to shrink your inserted pictures).
If your question relates to the facebook graph API, or to any facebook programming, the SO will also help.
