Belarki, shucks
Lil, owe know, there goes your magic number
Let me just throw in my 2c.
I want to reiterate what Busty among others have said on the issue of people leaving. I

'd AusDD and it will always have a meaning for me, it is great in helping people get knowledge and guidance for safer drug use.
But as I grew older, my affinity towards drugs decreased. This happened for many reasons. But as I decided that semi-frequent drug use wasn't for me, all be it for reasons of quality, reasons of risk vs reward, and social reasons, my need to be part of AusDD slowly decreased. I am all but happy to answer any HR questions about drugs I know about. However, I couldn't be an active member of AusDD as it was making it extremely difficult to slow my drug use. So I made a choice, and this choice had nothing to do with the quality of posts in AusDD, they are always great quality. I know a number of members who have similar stories, and maybe of these members seem to be the people you are hinting at. Let AusDD be what it wants to be. It will be what it is, a great resource for like minded people to help each other, and I think that is amazing regardless of how many posts are day are made.
To the OP. Your posts remind me of the old joke: "How many ravers does it take to change a light bulb? 6, one to change it, and 5 to winge and complain about how the old one was brighter, better and more colorful."
Goodluck AusDD, one day I'll post my thoughts on the illusions of the casual drug user, one day.
