Flickr, YouTube, and Pinterest can make a difference too. WordPress Social Timeline is handy plugin that lets you retrieve your activities from different social networks you are involved in and share them on your website:

It has multiple styles for displaying your content. The script does allow you to limit the number of feeds that you retrieve. What’s neat is you can use this as a widget in your sidebar. Filtering options are provided too.
