>> I'd like to hear it from the community: what kinds of applications and software tips do the nascent 'desktop Linux user' base want to read about? >>
Typical desktop users (not of the geeky persuasion) use browsers, word processors, spreadsheets, checkbook managers, e-mail clients, IM applications, media players, photo organizers, photo editors, CD/DVD burning software, games. We like to learn easier ways to do things, file manager tips, how to set up and deal with home networks both wired and wireless, simple but handy terminal commands like df -h. More advanced Linux users might like to know about the different desktops available such as descriptions and objective comparisons of KDE, Gnome, XFce, IceWM, and others. I would be lost without Tuxcards. People want to know about Wine and Crossover Office and other ways to run Windows programs they can't, or don't want to, do without.
Lots of people want to make slide shows of photos they can burn to a CD or DVD and they have videos or VCR recordings they want to transfer to DVD. They want to rip CDs and turn their music files into formats that their MP3 players can play.
That's off the top of my head. Take a look at http://tuxmagazine.com/
and see the kinds of things the late TUX Magazine covered. I always thought TUX was too KDE-centered, was a little too allergic to sensible use of the command line, and didn't go into enough depth in its articles. However, TUX covered things "regular users" are interested in. There is a download page at https://secure.ssc.com/allsubs/tux.php?action=show-downloads
but I don't know if a non-subscriber can download all the issues or just one as a sample. Since the magazine is now extinct and people can no longer subscribe, I'd hope people can download as many issues as they want.
Let us know when we can read your articles on Newsforge. I hope you make lots of money!
