If you're a technical worker, your colleagues may disrespect you unless you're running Linux. Share scripts you've written with others and study scripts written by others. Above all read, communicate, and share what you've learned and what you want to learn. As I see it, Linux is more a community than a product or technology. To use Linux effectively, you need to be a part of the Linux community.
Communities thrive based on service.
Spending time answering newsgroup queries posted by clueless newbies is a good way to initially participate in the Linux community. If you've successfully installed Linux, you can help others who haven't been as successful. Most newbie problems are pretty simple, though they may seem simple to the newbie only in retrospect. If you give useful advice with patience and courtesy, you've made a friend and you've enlarged and enhanced the Linux community. Not that you should necessarily devote the remainder of your file to answering newbie queries.
