Terribly late to the party, rude of me, I know.
I agree with Steve, it seems to come in waves. It is a bit shocking that people think that posting a question like "how do I do a backup" will get them a quicker response than if they just typed "backup" into the Books Online. Also, how did they know to come here? They did enough work to track this site down, but couldn't do enough to open up the help file. It's all a little baffling.
However, I think of it as a sign of success for the people around here like Jeff, Gail, and Jack. In some ways, they are providing better information than the BOL (even when it's just copied from there) because of how they respond. Patience, kindness and scary depths of knowledge seperate out those very few at the top from those of us who just enjoy hacking around. You guys are just victims of your success.
