From a shoppers standpoint, retailers took the Twitter plunge this year and really stepped up their game. Nordstrom has done a good job with updating their audience as has outdoor shopping center, The Grove in Los Angeles.  Although the promotion is now closed, Sephora’s Sephora Claus campaign granted a beauty product a day wish to 30 deserving customers and even added a $1 charitable donation from every purchase in the last few days of the promotion.

Customer service is playing a big role on Twitter as well. In a previous Digitally Approved post (Customer Service in the Twitterverse), the efficiency of the @BoseService team was discussed in connection to resolving a consumer issue that wasn’t even posted on their specific page nor did it have a # tag.  Nice looking out for your customers Bose!

Massive shoe retailer Zappos.com is looking out for their customer base on Twitter by offering support and positive service, big box retailer Best Buy’s Twelpforce quickly trouble shooting and responding to product questions, and restaurant chain, California Pizza Kitchen, recently sending a follower a $30 gift certificate because of a bad dining experience. In an era of questionable customer service, big thumbs up to our Tweeting retailers for really good customer service.

Couldn’t leave our Tweet round up with out mentioning some of the best in celeb and athlete musings. Sitting at lunch today a few Fanscapers were talking about TV of all things and the Christmas episode of Always Sunny in Philadelphia came up and then turned to Danny DeVito’s Troll Foot diaries on Twitter. Will admit, didn’t really know about this, but hell if this ain’t some funny stuff. He takes pictures of his Troll Foot in various places and at various events then posts them to his Twitter.

For some time now I have been raving about the one and only @OGOchoCinco.  He can be very profound like he has been the past few days in connection to the death of his friend and teammate, Chris Henry, but he can also be ridiculously funny (and sure a little self-serving) as well.

You could be one of Ashton Kutcher’s more than FOUR MILLION followers, keep up with the Queen of all Media, Oprah and learn about the Carl’s Jr. menu from  Kim Kardashian, but you’re not going to get the non sequiturs like you could by following Rainn Wilson (of The Office fame). He can easily go from apologizing for being a downer and sharing his experienc in Hati to this:    

Like stated from the onset, 2009 was pretty darn Tweet-tastic. Way too many amazing people, brands and retailers to list, but hopefully this little Best of gave you a few more places to check out or think about.
