One feature that has received a major upgrade in 2013 is the activity feed and microblogging infrastructure. The primitive functionality in 2010 has been replaced with functionality that you would expect of a social computing platform.
The information being published in the activity feed is determined by privacy policies and what you have chosen to expose. The first time you access your My Site, you are asked yo updated the privacy settings.
To start things off, here is a picture of the updated activity feed.
It’s possible to reply and like status updates. It’s also possible to select different views to show different types of activities. i.e mentions.
Using the @notation, it’s possible to mention other people. SharePoint will then provide automatic completion. The # tag syntax is also supported where it will use values from the Taxonomy service.
Another aspect of the activity feed is the site feeds that may exist on sites that you follow. This could be various community sites. The site feed has to be explicitly activated since it’s not on by default.
Once this has been activated, you can cross post into any community you are following.
With this functionality, SharePoint is eating into the territory previously held by companies such as Newsgator. It will be interesting to see how they respond.
