Actually, certain types of forums, social or cultural movements, attract zealots like honey attracts flies. Part of the saving grace of Linux is that somebody with Linus' modesty and respect for others is at the center of it.

Personally I use a wide mix of operating systems and computing equipment. My most productive programming is in Assembly language on embedded Micros generally with less than 1K of read-write memory (32 bytes in some cases). I prize interoperability, and Linux dwells at the center where it comes to interoperability. It can be used as the "hub" for wildly divergent equipment.

There have been times when I have become somewhat of a zealot in public, but it's not something I look back on with any pride.
