One of the site I added to my RSS feed is called giveawayoftheday.com.  What the website does is it offers a software for download free each day.  Software cost is one of the most expensive cost of owning a computer if you actually purchase software for your daily usage.

Giveaway of the way provides a way for you to trial different software without having to worry about license.  If you are a software developer, it is a good place for you to provide some potential customers a chance to try out your software.  Overall, a total win win situation!
