What is your OSX uptime?
For my mini, it's currently closing in on 12 days. I usually only turn it off when I go out of town for the weekend, which I did 12 days ago. 
To figure out your uptime, open "Terminal" (found in Applications/Utilities) and type "uptime." You will get something that looks like this:

My iMac is about 18 days.
Just to note the longest uptime I have ever had was on a server running redhat linux with an uptime of 349 days and then the power went out

The average number of processes in the Mach run queue over the last 1 minute, 5 minutes, and 10 minutes. I might be off on the 5 and 10 minute business though.

Here's a detailed description from wikipedia.
This is what "man uptime" says:
The uptime utility displays the current time, the length of time the system has been up, the number of users, and the load average of the system over the last 1, 5, and 15 minutes.

Simplified, it means how hard the CPU has been working.
A load average of 1.0 means optimal CPU usage. (No time idle, but not overloaded either).
If the load is, for example 2.0, it means you should get a twice as fast a computer.
Anything under 1.0 means the computer is mostly idle.
Honestly, I'm surprised more people aren't posting their results. It's real easy to do!
but what's with the "2 users" ?
i only have 1 user set up.

Root is one user. Your account is the other user.
damn security updates that make you reboot
6:08PM up 99 days, 7:03, 1 user, load averages: 0.00, 0.11, 0.18
Yike, that means I should finally make the OS level updates ;-)
We found a forgotten Sun server at work that had a few years uptime. I also had a few years ago a FreeBSD server that got over 600 days. Updated, but not rebooted. When It finally crashed, it of course didn't boot anymore, because of all untested changes and updates. It needed many hours of hard work to get running and never was the same again.
Reboot when you need to. It's the easier way to check if your machine still boots after all your changes and updates. Computers boots so fast nowadays, that it's a non-issue.
on my iMac:
21:07 up 4 days, 12:52, 5 users, load averages: 0.39 0.22 0.20

Wrong, the word "user" is misleading. Uptime (and other similar system monitoring apps) displays how many logins are present:
The graphical stuff counts as one "user". Every Terminal window, ssh connection and so on counts as additional "users".
It doesn't matter how many user accounts are present. Also, daemon (server/background) processes are not counted as logins, because those are detached from the login session that launched them (thus making them background processes in the first place).
I'm curious about things like this too. I think I even asked a similar question, somewhere at one time. I think 30-40 days was my maximum. I try to restart only for software updates.
