Facebook Groups Adds Dropbox Integration

Now if you want to share files with friends via Facebook Groups, you can do so via Dropbox.
“When the owner of the file makes updates, those updates will also be shared back to the group. And, just like other posts to Facebook Groups, people can like or comment on the content,” a Facebook representative told Mashable.
Since edits are shared directly back to the group, the functionality could be ideal for group projects where several people need access and the information is constantly changing.
Dropbox and Facebook also see the feature being used to share things like videos of a birthday party with your “family Group,” or class notes with a study group you have on the social network.
Documents, photos, and videos can all be shared from your Dropbox account onto your group’s wall, and all of that content can be viewed via web as well as on a smartphone or tablet.
Facebook rolled out file sharing for groups in May of this year. With the feature users can upload file types up to 25MB in size, excluding music and executable (.exe) files.
To get started using Dropbox with Facebook you just have to click the “Add File” button on your Group’s page and then link your existing Dropbox account (or create a new one).
The new feature will start gradually rolling out to Facebook users Wednesday.
Do you have the new Dropbox functionality in groups yet? Let us know what you think of the new feature in the comments.

Tumblr Passes Pinterest in Unique Visitors

Having recently surpassed MySpace in terms of traffic, Tumblr is moving up the list of the most popular social networks in the world.
Between July 2011 and July 2012 Tumblr’s monthly unique visitor count increased by 100% to 26.9 million, as Marketing Land reports.
This puts Tumblr, the five-year-old microblog founded in New York, neck and neck with Pinterest which collects more than 23 million uniques a month, according to statistics from Site Analytics which tracks how many visitors sites collect in the U.S.
In July, Tumblr collected 6.7 million mobile visitors and 24 million search visits.
In May, Tumblr broke into comScore’s list of the top 50 U.S. web properties, edging out Target and Discovery Digital Media for spot 47. The top social network on the list was Facebook at number 4 with 159 million unique visitors for April 2012.
Tumblr currently hosts 74 million blogs and 31 billion posts. It collects about 100,000 new blogs every day.
The top social networking sites in the world in terms of visits are Facebook (7 billion), Twitter (182 million), Pinterest (104 million) and LinkedIn (86 million), according to Experian Hitwise.

The Winklevoss Twins Are Backing Another Social Network

Tyler and Cameron Winklevoss, best known for their disputed role in the creation of Facebook, are backing another social network, this time for professional investors.

The twins have sunk $1 million into SumZero, a social network created by Divya Narendra in 2008, according to The Wall Street Journal. Narendra allied with the Winklevosses in their fight against Facebook CEO Mark Zuckerberg over the claim that he stole the trio’s idea, which eventually became Facebook. The battle, dramatized in the movie The Social Network, resulted in a $65 million settlement for the Winklevosses, though they have unsuccessfully sought further damages.

SumZero describes itself as “the largest online community for hedge fund, mutual fund and private equity professionals,” and has users from funds including Greenlight, Pershing Square and Weiss Asset Management. The site caters to employees on the “buy side” from mutual funds, hedge funds and private-equity firms. The site bars those from the “sell side” such as Wall Street banks.

The twins, who have since starred in a Wonderful Pistachios ad that poked fun at their image, told the WSJ that they are back in the game. “The band is back together,” Tyler Winklevoss told the publication. The news comes after the pair announced the creation of a venture capital firm back in April.
