We Love HootSuite. It is Our Goto Social Networking Tool
We've used HootSuite, https://hootsuite.com, for some time now and love it. Simple to use, powerful features, including a URL shortener, and a dynamite dashboard. Who could ask for anything more?
It has a great scheduler, and a HootLet Add-on for Firefox which we use a great deal. With this Add-on we can add anything we find interesting to our social media publishing stream.
We've used other tools, but HootSuite is our favorite and we no longer use the others.
