Twitter co-founders Evan Williams and Biz Stone have been busy bees at Obvious, the umbrella corporation they founded to “do various things”, one of which was a secret project that Williams hinted at back in March of last year.

Yesterday, Williams announced Medium, a new tool that aims to rethink online publishing and allow people to “choose the level of contribution they prefer”.

Medium is a slickly-designed platform that allows users to share content – text, pictures, and so on – which are organized into “collections” that are defined by a theme and a template. Williams explains more in a welcome post on Medium.

Collections give people context and structure to publish their own stories, photos, and ideas. By default, the highest-rated posts show up at the top, helping people get the most out of their time in this world of infinite information.

Together, the contributions of many add up to create compelling and useful experiences. You may be inspired to post one time or several times a day—either way is okay. If you’re more ambitious, you might create a collection of your own.

Medium looks fantastic, although it is a little bare bones at the moment.

Anyone with a Twitter account can read and give feedback on Medium, but posting is limited to a (very) small invite-only list of friends and family. No word on when this will all be opening to the common or garden public, so it might be a while until we know if this Reddit-meets-Pinterest idea has any serious legs. But it certainly looks nice.
