Obviously there is significant overlap between scifi.SE and movies.SE.
Do you spend a significant amount of time on movies.SE? Why or why not? How is the other site different in culture? Content? Quality of questions? Quality of answer? If you spend time on both, how do you decide where to post?
(This is purely discussion, sorry if it's considered off topic -- frankly I don't understand want would be considered off-topic on meta.)
