I love HootSuite! I'm a Marketing Managers responsible for all of my company's social media, as well as a number of other functions (events, landing page and email copy, blog, etc). HootSuite makes it so easy to do the social part of my job well because I can schedule my posts in advance, shrink my links right in the platform, gather my analytics, etc. In addition, they integrate with Get Satisfaction customer communities (disclaimer: I work for GS), so when someones gives us praise on Twitter, I can pull it into our community for everyone to see/search for. All of this, right in the platform.
