I was playing around as usual opening apps and closing them while listening to streaming in iTunes....
I have MEMORY MONITOR installed in the Dock. I glance over it and see I have practically used up all my free Ram. This usually happens after a whole day with it on and using it. A restart always brings your free memory back to normal.
Here is where it gets interesting..
I decide to open Macjanitor and run it. Meanwhile I'm looking at MM in the dock.
Nothing happens at first as the daily script runs..so I clear it and goto WEEKLY.
Wow, almost imediatly I see the free memory start climbing from 50 megs to 435megs!!!! Just by running the script!!
What I had to restart to accomplish before I can get the same just by running the weekly script.
By the way I run the script manually about once a week.
Please comment on this.

my memory usage didn't change, but it is good to know that these tasks should be run!

Isn't it possible that the week's worth of log files & etc. are all paged out in VM, and the housekeeping scripts clear them out as they are archived?

Why would you want to "free" memory again? That's what the kernel's memory management is for.

You DONT want 'free' RAM. 'Free' RAM is wasted RAM that could have cached apps / libraries in it. The more RAM used, the better. The system attempts to use exactly 100% of your RAM, no more. That is the BSD model.
OSX loads stuff into RAM and does not load it out until the space is needed by something else.

I wanted to second (third) the two previous posts. The system will make use of all of the memory that you make available to it. BSD does this. Linux does this. It's normal, and it's good.

Those /etc/daily and weekly scripts don't seem to do much that affect system performance in a noticable way. They are needed to keep certain things organized, and logfiles from possibly getting too big, but I don't see anything that removes scripts from the VM

I agree with the above posts. Free RAM is wasted RAM. Your RAM is MUCH faster than your hard drive. If you have free RAM, why not just cache the frequently accessed stuff on the hard drive to the remainder of the RAM, or some other efficient use of that RAM.
Why, for example, would you want a gig of RAM if you expect three quarters of it to be available? If that's the situation you expect, why not just stick with 256 MB of RAM? Then you'll have 256 MB used--exactly what you were expecting. Unlike other systems, on OS X, more RAM=faster computer. You can never have too much RAM.
