Google Cheat Sheets

Oh Twitter, you never cease to amaze me.  There are so many resources I've discovered on Twitter that are too numerous to note.  But one I stumbled across today (do you stumble across tweets or do they drop on you?) was from a blog called Shake Up Learning.  The site has a bunch of great resources but what I focused on were the Google Cheat Sheets.  If you're a beginner jumping for the first time or an experienced user looking to hone your skills they are a great resource.
