Genre within the community

After some exploring, I've found a different type of genre within my community.  While most of the community consists of one person writing a blog post/article/Tweet, then others responding, I stumbled upon a kind of forum on the popular Feminist website, Jezebel.  On the home page are a bunch of recent articles by the most popular authors, all of which have various comments on them.  This is the most common way that my community interacts on this specific website.  However, after some exploring I found 2 more ways that members could interact:

•  The Powder Room, where members of the community can write their own articles and upload them themselves
• Groupthink, where members do not write articles, but can simply post a few sentences that they want the other members to reflect on or offer their input for.  

I think these are great--especially the Groupthink part of Jezebel's website.  Maybe someone may not have the resources to write a full article, but this is a way that members can still interact with each other just for fun, it seems.  Most of the submissions on group think are just everyday things that someone would like to talk about--the new Grand Theft Auto game, questions about the dating site OkCupid, someone's grandmother being assaulted, or even just someone getting invited to their 10 year high school reunion.  This is the more personal part of the community that I have been searching for--definitely more intimate than comments on articles or blog posts.
