As December rolls on, we will undoubtedly be inundated with year-in-review materials – “top this” and “best of that.” Some of this is incredibly uninteresting, simply due to the fact that it feels so obligatory. But Twitter’s kick off to their year-in-review happens to be a great story.

That’s because it has to do with Twitter Stories, Twitter’s initiative to showcase the more human element of Twitter by highlighting various interest stories about how Twitter has impacted the real world. For instance, one of the top “Twitter Stories” from November told how a man saved his mom’s independent bookstore from going under with a single tweet.

Part one of Twitter’s year-in review doubles as December’s best of Twitter Stories, and they are choosing to highlight one story about a homeless man who used Twitter to reconnect with his estranged daughter.

Oh yeah, and he meets his grandchildren for the first time. It’s sappy and such but dammit, it’s the holiday season!

A New York-based group that helps the homeless connect through social media provided a man named Daniel with the tools to get started on Twitter. One thing led to another, and his daughter found out about his attempts to contact her through the site. Check out their story below:

The December edition of Twitter Stories highlights ten remarkable moments of 2011. From the man who inadvertently live-tweeted the raid on Osama bin Laden’s compound to the homeless dad who was reunited with his daughter after years of separation, this list, which doubles as the annual “Year in Stories,” chronicles how people use Twitter to make a difference in ways that are both personal and universal.

There will be four more parts to Twitter’s year-in-review, all to be unveiled at undisclosed times throughout December.
