In 'uptime' output, what does "load average" mean, and when does the number become "bad"?

According to the AIX man page for the 'uptime' command, the following is true:
"The uptime command prints the current time, the length of time the system has been up, the number of users online, and the load average. The load average is the number of runnable processes over the preceding 5-, 10-, 15-minute intervals."
My numbers are usually below one, so I haven't been concerned. Lately, the numbers are sometimes getting higher.
Can you tell me what the "load average" or "runnable processes" means, and at what point the number becomes "bad"?
In other words, is 1.5 okay, but 5.3 bad? The man page is not very informative on this issue.
