Keep in mind that unless you're super good about maintaining your system, a reboot every few months is often a good thing anyway, it tends to highlight hardware issues that often only occur in high stress situations such as booting, and services that have been installed and are running but aren't set to start on boot (two things off the top of my head)

I would agree that every 2-3 weeks is too often, but once every 4 to 6
months is probably wise. If this isn't possible then you need to have
redundant systems IMHO.

I also have a problem with letting the *typical* PC system run this long without a reboot. The problem is most PCs don't have ECC memory, they don't even have parity-check memory. And the HW was designed with the Windows mentality that you shut your PC down at the end of the day and re-boot the next morning, so we don't have to worry about a little memory "bit-rot" which might take weeks to show up :-)

Now, if you have a server that needs to run forever and be re-booted as little as possible, then if it's so important a resource it should have ECC memory and perhaps a hot backup machine. If it's one of the several ultra-cheap workstations I tinker with at home, then I think a weekly re-boot is no inconvience and perhaps a good PM.

Besides all that, between new kernel releases and "optimizing" the latest kernel to my hardware, I'm lucky to go a day or two between re-boots :-D
