Looking around for good Linux applications or perhaps some tutorials? You'll find many applications in our database here at OStatic (just click on Software and enter your request in our Search field), and I've also been looking into some useful new resources.
Tuxsoftware is an interesting new pit-stop. On its home page today, you'll find featured applications such as Flyback (similar to Apple's Time Machine backup utility), and Pidgin (instant messaging). You can also search for applications, although I don't see any citation of how many there are in the site's database.
