I recently started using another aspect of social media, a social software site called wakoopa. As with so many of the other social media sites I use, I was introduced to this by my son @chronotope on twitter. This site analyzes and tracks the software you are using on the computer you run it on. It tracks both the active application and the background applications. Not only can you review the applications you use, but you can also see other reviews and find other software. One of the options lets you set the site to alert you of software updates.
When you log in and start tracking your profile will look something like this. The top half shows your favorite applications and what you say about each one (you can mark anything as a favorite app), below that are the top ten pieces of software, according to your usage, divided into categories of the past week, past month, and newly used apps. Next to that is some basic info about your software usage and your level of usage according to how much you contribute, how many different apps you use, reviews you write, screenshots and icons you upload, etc.
The next part of the screen shows a usage history graph and some recently used apps (note that most stats are 1-2 days old). You will also see a message section, which can be used to communicate with people you have friended, and some of the point awards you have received to change your level. Below the Awards section is a section showing the most recent reviews you have submitted.
You can see what new software is being used and what people think about it. When you check out a piece of software on wakoopa, it lists other software that does the same thing. this can be real handy if you know a piece of commercial software but want a similar free version. Or if you are having trouble with a certain piece of software another app may do the same thing without giving you problems.
Other users reviews can be quite instructive and helpful in finding the appropriate app to use in any circumstance.
