I stumbled upon this Web site called the Open Source Alternative. The entire point of the site is to identify open source alternatives to common commercial (or just not open source) applications. For example, if you need something like Visio, but don’t want to give Microsoft any more money, you can check out Dia. The osalt.com site is pretty simple, well organized, and easy to navigate. It includes descriptions of the various software, including the operating systems they run on and user reviews. As a person that prefers using open source software whenever possible, it’s nice to have a resource like this available when my next need arises.
