Each user needs a single place to identify all the content/items which the user follows.
The concept of following is an obstacle to my users and me. If somebody has an easy description, you are welcome to provide this ;-) - post a link into the response. The only way for me (as a user) to determine which content I follow is first of all to go into different areas mostly item by item. Additionally there is the option to check why I follow actual updates in my stream by using the "stop following" option as soon as an event is shown in there. This is either very cluttered or does not really explain why and when I did set the following option.
What each user needs is a place to identify all of the followed items (people, tags, community, apps, files, ...) . This should include which property I follow (e.g. tag or person), since when (if possible) and have a way to cancel one or several items at once.
