Six years ago today, some unruly trees in Ohio plunged 55 million people into darkness during the Northeast Blackout of 2003. While inconvenient, it forced people out of high-rise apartments, neighbors bonded, guitars went acoustic, candles were lit, and there might even be a higher than average number of kindergartners this year. Here are our new beginnings from this week:

• Cheapskates rule: There's nothing like nuked portfolios and pink slips to make couponing de rigueur. This recession has spawned a generation of proud penny pinchers who enjoy the hunt for great bargains, and the refreshed Yahoo! Deals makes that even more sporting fun. In addition to daily deals, weekly electronic circulars, and online coupons from major retailers, you can now find great local bargains with coupons for groceries and neighborhood stores. You can even share your dollar-saving discoveries through social tools like Twitter, Facebook, Digg and Delicious. Get your save on. More here.
• Trash talking mayors: Politics and fantasies should rarely mix. But mayors from 11 big football cities are letting their imaginations run wild as they pick their teams for the Yahoo! Sports Fantasy Football Mayoral Face-Off. From San Francisco to Oakland, Green Bay to Buffalo, mayors are squaring off to see who can assemble the winning team. What's in it for them? A check for $15,000 to benefit their favorite local sports charity. What's more, the city with the most votes from football fans scores another $15,000. So go hit the polls now. More here.
• Measure your mojo: If you know how to retweet your @replies with a hashtag, you're on Twitter. But do you know what kind of Twitter user you are? In celebration of the launch of our new Yahoo! Homepage, we've launched Know Your Mojo with a sophisticated pipe thingy that analyzes your account and spits out your social mojo. If you're a Crowd Pleaser, you're into hashtags. If you're a BFF, you're big into @replies. If you're a Wall Flower, you seem to have forgotten how to type. We'll also recommend what websites you should add to your own Yahoo! homepage to help feed your mojo. We're a Concierge. More here.
• You're two-faced: Speaking of customizing your Yahoo! Homepage, we've developed a Facebook quiz that acknowledges that there's more than one side to each of us. In our Split Personality quiz, you'll answer ten multiple-choice questions to determine whether you're more like Tiger Hilfiger, Galileo Cronkite or Bono Rockefeller (etc.). And then we'll suggest websites to add to your Yahoo! Homepage that match your dueling passions. What's your split personality?
