I've ben using Linux since February 2007. I'm not an expert, but I at least can fend for myself (for the most part). I switched to Linux after many frustrations with Windows and Microsoft. I have not found many working Linux distros, but there are a select few that actually work.
I am the main webmaster for Ark Linux, a stable and well formed distro for non-technical users that retains the flexibility and power for veterans and hobbyists. I will, on occasion, use Yoper Linux and Debian.
I enjoy Linux, and am hoping to add Vector to my lineup because it is one of the only few that still has KDE 3. I find KDE 4 very unstable and lacking in some of the old KDE 3 features, and I'm not a fan of GNOME (it's a good desktop, but a bit too limiting in features and customizability).
