The ten categories would be:
Word processing and publishing
Media players (audio and video)
Games and entertainment
Internet clients (desktop)
Programming and development
Images and graphics
Now the hard part would be to draw up a list of the best five apps for each category. For the purposes of this list, it would be a good idea to limit the contest only to Open Source (that means no Opera, Acrobat Reader or RealPlayer - sorry folks!). The other limiting factor is that this is open only for desktop Linux apps, so enterprise Linux apps and server software are excluded from this list.
I welcome nominations in all categories. Please post your nominations as comments here so that I can draw up a final list soon!
