Tuesday evening, Twitter and Blogger cofounders Evan Williams and Biz Stone (and team) stealthily released a preview of a new digital publishing platform called Medium.

While it’s still very early and full release is still quite a ways off, there are a few reasons why we’re already getting incredibly excited about the potential of the “platform to change all platforms.” You can check out Ev Williams’ preview post as well as take a peek at some of the first collections on Medium here.

A few early possibilities, predictions, and premature excitement-enduced proclamations of/for Medium:

• Medium looks to be designed to accommodate all levels of involvement – from obsessive content contributors (few) all the way down the ladder to passive wanderers & watchers (most)

• With the ease of connectivity via Twitter accounts (and perhaps others down the road), usage scaling could be fast and furious

• Privacy looks to be easily controlled — collections will most likely vary from closed family/friend words and photos to completely open content based on broad interests and topics

• It takes the visual design and appeal of properties like Instagram and Pinterest to a whole new level

• The ease of contribution, sharing and consumption seems very similar to that of Tumblr

• The user controlled rating and organizational structure is similar to Reddit — which means beautiful, meaningful content will bubble to the surface of any collection while boring, meaningless, overly self-promotional, etc., etc., etc. content will be pushed to the bottom out of direct consumption paths

• It is the perfect mashup of content aligned with our social graph and interest graph (please excuse the use of the word social, Mr. Williams)

Disclaimer: The bullets above are highly speculative and should each include caveats of “could be,” “maybe… just maybe,” and “please, oh PLEASE, let this be true.”

We’ll keep a very close eye on the new publishing platform that [insert caveats here] will change everything. What better brand name to change the content publishing and consumption game than “Medium?” This team did it with Blogger. They did it again with Twitter. Who’s to say they won’t do it again with Medium? [caveats][caveats][caveats]
