Is cross-posting a question on multiple Stack Exchange sites permitted if the question is on-topic for each site?
The question I basically intend to ask here is that even though there is a great probability of a question getting an answer if it can be viewed by users from multiple Stack Exchange sites, why is there no facility as such?
For example, if I post a question on StackOverflow related to some CSS/HTML issue I'm facing then the question is restricted only to the users using Stack Overflow though there's a probability that someone at Webmasters StackExchange might also know the answer.
Why isn't there any facility that a question that has tags mutual to two or more StackExchange networks be implicitly shared on all those networks?
Just a humble suggestion on my behalf. Thanks for your insight in advance.
