Twitter co-founders unveil latest social projects Branch and Medium

Two of the co-founders of Twitter have announced details of their latest social projects, called Branch and Medium.

The services have been dreamt up by Evan Williams and Biz Stone, who now work at start-up idea firm The Obvious Corporation, with both services appearing to be inspired by other popular social tools dominating the web.

The first service, Branch, is designed to let web users host more in-depth conversations with people they consider experts on a subject, while other web users can view the content of those discussions.

"Between articles, blog posts and tweets, the internet is dominated by monologues. So we want to build a home for dialogues online, by combining the intimacy of a dinner table conversation with the power of the internet," wrote head of product at Branch Josh Miller in a blog post.

These conversations can be viewed by anyone online, although only those invited to join in the discussion can post content, differing slightly from the Quora service where any user can ask and answer questions on any topic.

Meanwhile, Medium appears to mimic services such as Tumblr and Pinterest by providing a means for users to display and share content, with the option for others to add content that can be voted on by other users.

"Medium is designed to allow people to choose the level of contribution they prefer. We know that most people, most of the time, will simply read and view content, which is fine," explained Williams.

"If they choose, they can click to indicate whether they think something is good, giving feedback to the creator and increasing the likelihood others will see it."

Both services are currently invite only and it remains to be seen if yet more creative social and sharing tools are what internet users and businesses want.

However, many will no doubt be intrigued by the two offerings given the success and widespread use of Twitter in which Stone and Williams were so integral.
