For those who work with SharePoint, you may want to take a look at the little app Microsoft just pushed out called SharePoint Hub. It features the SharePoint official blog, Twitter and Facebook integration and basically keeps you abreast of what is happening in that small corner of the world. By no means is it a killer app, it's still a neat little info app that we imagine some of you will make use of:
"Connect to the Microsoft SharePoint community via your phone. The SharePoint Community app connects you to the latest information direct from the SharePoint product group blog, as well as information on news events. You can also connect directly with the SharePoint community via Facebook and Twitter."
