As many have emphasized, Linux is exceptional in the server market. For consumers however, many do not realize servers can be very small scale and reduced to embedded devices. I’ve been working on a Linksys Network Storage Device for my home lan. Basically the device is a Linux server running on 133Mhz ARM Processor with 32MB of ram. However it comes with a 100Mbit network port and 2 individual USB2.0 ports.
Quite possibly the most useful Linux and Fedora forums on the internet are LinuxQuestions.org and FedoraForum. I prefer the first one since it has been around much longer and has a great deal more content for Linux in general (not just Fedora). However the second one has been dubbed the “official support forum” for Fedora, so I guess it will have quite a good number of helpful people as well. Of course, my main gripe with forums in general is having to continuously checking for updates on threads, making sure you ask the “right questions” and dealing with arrogant admins.
One of Linux’s many strength’s is its highly suitable web hosting options. Primarily Apache web server on Linux with various open source applications can provide cheap solutions for hosting needs. The most commonly used hosting option is Virtual Hosting through Apache. With a simple setup, hundreds of unique websites can be run with 1 single server machine. For about $100 (US) a year, you can get a good set of features from most providers.
