Well, it's not important because the difference, generally, between the Pi and a random computer is similar to that which can be expected between any other two random computers.
The thing with the newbies I get - they want to google "web server raspberry pi" and get a really quick and easy step-by-step, but I'd really like them to at some point get the idea that this is a general purpose programmable computer like their laptop, PC, phone, whatever, and that they should expect it to be able to do basically anything.
I get the benefit of the specific howto, but I've not yet found enough pi-specific problems to make me think that's more important than getting the idea that it's a proper computer and not just some cut-down thing that can only do a good enough impression of one to run a web server and python or whatever.
I'm not sure it matters more that you're using a Pi than it would matter which old laptop you're using.
And, when it's as low-level as simply making something work, rather than particularly optimising it (when the fact that it's a Pi or a 2003 T61 or a whatever do matter), I think that treating it as a slow Debian machine and finding a generic howto (or, better, a few generic howtos) is much more appropriate than insisting that you find a "How to install postfix and courier on as raspberry pi".
Obviously for troubleshooting problems the hardware's much more important, too, but so far I've just treated my Pi as just another Debian box and everything's just working.
Hm. Now that the link's finally loaded I can see that this is exactly the same link I posted a similar comment on on Reddit a few days ago, to which the author didn't take kindly. Hopefully I've made my case slightly better this time! :)
I'm really beginning to dislike all these "Set up the Raspberry Pi as a X" tutorials. I think they contribute to the idea that there's something weird and peculiar about the Pi, and give the impression that if you want a tutorial to do something on the Pi you need a "For the Pi" tutorial.
Couldn't we instead have a "Install Raspbian" (or whatever) tutorial and then try to push the idea that at the end of that you have basically a low-powered Debian machine and can follow any "Do X on Debian" tutorial? It seems that one of the wonderful benefits of Debian as a "universal OS" is that it doesn't matter whether it's on a Pi or a ten-year-old 386 laptop, it's another computer and almost everything is just an apt-get away.
I'm not sure where a GUI comes in handy here - it's not like there's any good GUI (in the traditional sense) tools for fiddling with webserver config.
Even were I to want one on a webserver on the localhost I'd probably just install webmin or something, which you can do equally well on a VM somewhere else.
