I'm amazed at how quickly I receive answers! What is it that people are doing? Is there some sort of monitoring program that beeps or something when a new question has been asked that is tagged with the subject that you specify?
I think F5 does most of the job. :)
But also and most importantly, there simply is an awful lot of people browsing SO at any given time.
Some people use the sort order newest question, look for questions they know something about and hope to type quicker than others.
Next question please.
