This week's social news: Diggbar, Twitter's value and more.

Luckie social media intern Whitney Sides returns with a new installment of The Social Pathology Report — and a new last name.

Happy Friday, and guess who's back?

Sorry for my lack of Luckie links last week; I got a little held up with nuptials, general happiness and, you know, things of that nature. I now have an added last name and newfound appreciation for all things people-wrangling and invitation-related. Let's hear it for being mega-social in my offline dealings as well. ("Chorus of "yays!")

Today, I'm back and full of fodder for the slightly techie, largely social folks out there.

And in 3... 2....

• FWD TO YOUR BOSS: A recent study found that YouTube and Twitter usage at work actually increased employee productivity by 9%. Huzzah! [Switched]
• Social bookmarking/link-sharing site Digg.com has finally gotten around to creating an official browser toolbar, shockingly named Diggbar. It lets you shrink URLs and share sites you like from within your browser window. [Mashable]
• COLLECTIVE AWW: Dueling wedding-themed apps on Facebook let you share and even plan your wedding on facebook. [Mashable]
• Have a favorite nickname you generally go by across multiple sites? Now, you can use a program to scan a multitude a sites to see if someone else got to it before you. [namechk]
• For those who always want the newest and best toys/technology, the founder of the Web 2.0 conference brings you his 5 favorites (courtesy of IBM, NASA and Google).[ReadWriteWeb]
• Who wants a free pizza? Well, tough, you slow-moving slacker. When someone figured out that early this week that an unauthorized "BAILOUT" promotion code could get you a free Domino's Pizza, word spread frighteningly fast on the Web. More than 11,000 free Domino pizzas were delivered before the glitch was stifled. [AdFreak]

And I'll close on a heart-flutter note to go with the awesome week I'm having....

• Insiders say that Evan Williams (the CEO, not the whiskey) wouldn't sell Twitter to Google for "even a billion dollars". Wow. For a company buzzed about for a lack of business plan, that's amazing. Hopefully he's "rich in love" like my mom & dad keep reminding me that our family is. Shrug. [TechCrunch]

If you have any tips or links worth mentioning, send me some social aggregation fodder via e-mail or on Twitter.
