You're encouraged to leave comments and discuss any of the resources on PeerSource: just click the Comments tab at the top of a specific resource page.
You can also rate and tag posts to help yourself and others find and evaluate content in the future.
Most content on PeerSource can be rated using a five-star rating system.
To rate the content on any allowable page, simply locate the row of stars at the bottom of the page, and "vote" by clicking on one through five stars based on your opinion of the content's quality and usefulness. One star is the poorest rating you can give content, and five stars is the highest rating. You can change your rating later, or cancel your rating at any time by clicking on the 'x' icon.
All ratings are anonymous, and users are encouraged to rate content honestly. Look to the row of stars at the top of a page to find that content's average rating.
Additionally, while searching for content, you can sort your results by their average ratings, to help you better find and evaluate new content.
A tag works like a simple label. Tags provide additional information about a post, and are helpful in grouping similar posts together into flexible classifications. They don't have to adhere to any predefined categories—they are uniquely applied by users. Because an individual's tags are shared across the entire community, adding tags to content helps to build an informal but effective classification system (sometimes called a "Folksonomy").
While browsing PeerSource, you'll see that tags are displayed in a "tag cloud," in which the font size of a tag reflects the number of posts to which that tag has been applied. This helps users to visualize the distribution of content across the site. If you're reading a discussion thread or accessing a resource and you'd like to find related content, try clicking on tags that other users have applied to the page you're on, and see what turns up!
You might tag a post, simply as a reminder to yourself, or as a helpful way to group posts together later. When your tags are combined with those from the rest of the community, they make content easier to browse, and add helpful keywords to improve search results.
It is a good practice to add a few relevant tags when making a new post. This will make your post more visible to other users browsing related content.
