It's always nice to just ask a question and get an answer. What's not as nice is to always have to answer the same question.
While I'm sure the specifics are different for everyone, I imagine the majority of us here have schedules much like yours. Popping in to post a quick 'please use the search' is just as nice for those folks as popping in to ask the question is for you.
If others have the time to do the legwork for you great; and I know we have some very helpful folks out there who can and will do that from time to time. If 'throwing a bone' by doing a quick search for someone is just as easy as posting a rebuke, then it's probably just as easy as posting the original question.
By the same logic, if you have time to frame up the question properly, wouldn't you have time to search?
All playing devil's advocate, as I know where you're coming from, and have been guilty of it myself from time to time. As you pointed out, there are SMEs here who wouldn't have to search at all... the answer is on the tip of their tongues. Still, this approach requires that these SMEs are generous enough with their time to post an accurate and complete answer to your question, which may take more time than a search in the end.
Each time they do this, they 'burn out' just a little bit more, until they realize that what they get from Army.ca is far less than what they're giving. At that point, we tend to lose them so I hate to lean too heavily on them like this. A better use of their time would be generating FAQs, editing wiki pages, etc. Then the response to many questions can simply be a link to a well documented response. Or even better, this approach may head off some questions completely.
That's why we've made the wiki editable by any registered user, and that's why many of the FAQs are started or maintained by regular users. (The Staff are here to police and organize, but are not here to be the SMEs on all things military.)
It all goes back to the same thing I've been saying: involvement
Without involvement by our membership, we quickly wither and die. I've seen a few new members use the site to work their way through the system and come back much later to 'repay their dues' by helping out. That's the perfect system in my mind.
