As the submitter, I should have elaborated in the main article so my apologies. We have ~100 users asking questions to helpdesk with an average of 5-10 questions a minute from those same users and it is being fielded by 2-3 actual helpdesk representatives at any given time.
That's a silly number for representatives to require answers for what are generally common-sense responses, I agree. While we streamline our helpdesk ticket process we will also be reviewing our training procedures to eliminate the questions that these people should be able to answer themselves.
While we could also just hire additional Helpdesk staff, it doesn't change the fact that Jabber is a terrible way to manage floor-level questions, especially when documentation is concerned.
