I see people adding tags in many different ways. Is there a proper one? For example I want to ask a question regarding motion detection. The tags that I found are the following:
motion × 25
motion-detection × 8
motion_detection × 4
#motion-detection × 3
Many questions tagged with 'motion' have additional tag 'detection'.
What would be the best way of tagging my question? Separate words? One word (motiondetection)? With or without a separator? Does # have any influence on tagging?
