I like how simple it is to use, all my posts are located in one place and are updated for me without too much fuss or hassle. It's easy to see at a glance what new things have been posted by other users and which ones deserve attention. The community forums can be helpful as well if you're not sure where to post something but there isn't any way of searching them so they don't feel very useful. There are some plugins available that allow additional features such as adding RSS feeds but those aren't always compatible with older WordPress versions. We've only used the basic version but Opennema seems to work fine once installed. I'm using it to publish news articles from our website.
