I've this question at stackoverflow and at serverfault: https://stackoverflow.com/questions/10579273/html5-video-browser-performance and here https://serverfault.com/questions/388971/html5-video-browser-performance#comment402270_388971 and I got insulted and downvoted and then closed? I'm just curious. Why this downvotes? And why is this question closed at stackoverflow? It's about html5 and I got my question about server? Why isn't this a programming question? Didn't I have enough reputation to ask this?
You should only ask practical, answerable questions based on actual problems that you face. Chatty, open-ended questions diminish the usefulness of our site and push other questions off the front page.
Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much.
If you're putting minimal effort into asking a question you expect someone else to spend hours or even days answering, you're showing some major disrespect for the folks you're directing the question at.
There are many people who dedicate their entire work day, every day, to answering the question you posed - and you expect them to write a book on it because you can't be bothered to do a bit of research on your own or even describe in detail what you're trying to accomplish?
I'm sorry, but that is completely unreasonable. Take a bit of time to think about the problem you're trying to solve before throwing it in someone else's lap, and when you do ask, have the decency to share with them first the details of what you're hoping to accomplish, the constraints you must work within, what you've already learned, and where you got stuck.
