Are you going to provide support for all the computer illiterates who switch to Linux based on articles like this which work on fear that know nothing about their systems?
They'll be coming to ask about how to get their cable modem or winmodem hooked up (but not here of course, as they'll not be able to get online...), getting AOL 7 (or whichever version) to work, playing the games they had, etc.
Their ISP most likely won't offer support either, there're just too many distributions around each of which works just so slightly different to make it practical. "go ask in a newsgroup" will be a much heard response, a newsgroup they can't get to because they can't get online (and they would likely not get a useful response anyway, probably being told to RTFM pages for some package they need to install without being told how to get that package installed in the first place).
Linux is nice for the techies among us, but not for the average user.
"Linux on the desktop" has been heard shouted for many years as coming "this year", and it's not a bit closer than 5 years ago when I first dabbled with it (dabbled, because until recently I couldn't get a machine working stablely enough to be of much use, mainly hardware that wasn't recognised and even the machine I now have running Linux needed new hardware because there was no way to get it all working together due to broken support for some of the devices in different kernels).
It took me 2 weeks of research (lucky for me I have a machine running Windows as well so I could get online to do it and download the stuff I needed) to find the solution, which lay in a different network card with a different driver and a new version of the kernel.
I severely doubt my mother would have been able to do that...
