links for 2010-04-10: Corporations that don't pay taxes; Site speed affect search results; Microsoft and Cloud apps

• Outrageous: Exxon Mobil Paid No Income Tax in 2009 - I am no tax expert and I'm sure there is some valid reason for it, but it just seems wrong.
• Using site speed in web search ranking - Too bad we don't have such incentives for native apps too!
• 2010 versions of Office, SharePoint pressure Google to respond - But still has a different approach than Google if this is true: "... gaining access to the browser-based versions of Word, Excel, and PowerPoint will require users to have access to SharePoint 2010 and a license to Microsoft Office 2010".
