I'm interested to hear other reactions to this question, but my opinion is that you should pick the board that best fits the question and ask your question in only one location.
Users who have cross-talents tend to check multiple boards, and the one who can help you will most likely come across it if you put it in the most appropriate place.
What you normally see when people do post in multiple boards is that someone will answer it in one place and post a reply to the duplicate threads saying "This was answered here" and link to the other thread.
By all means, if you don't get an answer in one board and feel that another board would have been more appropriate, posting a second time is a valid option.
There is no automated means of posting to multiple boards simultaneously.
Thanks!
