Twitter founders Ev Williams and Biz Stone have a new venture that is targeting the publishing industry.

Callled Medium it brings together blogging, Stone and Williams both worked at Blogger, with community and curation.

The founders say they “felt compelled to build a content network for the technology age we’re living in now, and we have a vision for what publishing should be”.

On its website Medium argues there much room for improvement and innovation in the publishing space right now “because it’s operating on outdated legacy concepts. Everything from the way we consume content to how that content is created needs re-imagining”.

The name of their new venture obviously suggests it sees a space between the user and the those creating content where it can flourish. Having created the network in Twitter the pair are now gunning for content.

The way Medium works is that all posts are organized into “collections”, which are defined by a theme and a template. Readers who like a post can give it positive feedback, increasing the likelihood that others will see the post.

It feels a little like Tumblr and is nice and simple in terms of design. Williams says “that good design supports the purpose (not just the appeal) of content, so Medium is diverse in look and feel—ranging from different types of articles to images to, eventually, much more”.

While it is not yet open to all Twitter users can look at and respond to a set of collections, including “The Obvious Collection“ and “The Writer’s Room“.

What do you think? Is there room for another blogging and curation service?

Possibly, although interesting to note that Twitter bought blogging and sharing platform Posterous that was once seen as a competitor to Tumblr.

Having done that Twitter’s founders are off working on another way for us to share and curate.

In a post on Medium, Williams said: “We haven’t tied everything in Medium together yet, partly because we expect our ideas to evolve rapidly as we experiment and learn from usage.

“Our philosophy is that quality begets quality, so we will grow Medium smartly, ensuring that our platform is valuable to everyone in this increasingly mobile, connected, and noisy world.

“As of today, everyone (with a Twitter account) can read and give feedback on Medium. Posting is limited to a small invited list of friends and family, which we’ll be expanding rapidly—soon, to those who have registered, so if you are interested please do so.”
