Here's the description from the site that nicely sums up what it does:
"The main purpose of Simplehelp.net is to help beginner-to-intermediate computer users learn how to do various things with their computers. Simplehelp.net teaches a wide variety of topics to all levels, such as troubleshooting email, preventing spam and removing spyware."
Using tips, tutorials and articles the site answers questions in an easy to understand format. Beginning computer users will feel comfortable here since the site is geared towards folks who are starting out and have questions but don't know where to go to get answers that are compatible with their level of knowledge.
That said, I often find interesting and useful information here, and the format of the site rates high on my usable and looks great scale. Advanced users might want to read the "About" section for some interesting tips on how the site can be useful to you.
Hope this helps someone,
