Every week, we bring you a link roundup of some of the excellent news, tips and tricks and how-to guides out there in the Mac blogosphere. This week’s group:

1) From MacWorld, the 7 Best OS X Tricks You’re Not Using. A few of these were new to us, including force quitting the application that you’re already in. Very helpful!

2) Also from MacWorld’s excellent At Work, a test of the eight most pervasive energy-saving techniques — learn what does and doesn’t decrease your energy usage with your Mac.

3) And from the Mac Observer, How to Stay in Control of Your iCloud Photo Stream. We’ve said before that iCloud gets us more questions than almost anything else in the Mac World (behind only Apple IDs), so we love seeing guides on what to do.
