I'm not sure of the details of the equity, but Steemit inc. doesn't really turn a trading profit outside of the Steem tokens as far as I am aware - so in a sense I imagine the price of any stock in steemit inc. is effectively relatively moot in comparison to Steem tokens, which actually have value. That could well be why I never usually hear anyone even mentioning the subject. It would be interesting to see accounting for Steemit inc. - I just did some searches but couldn't locate them in D&B. If all of Steemit inc's work goes towards raising the price of Steem, but Steem isn't actually owned by Steemit inc. then the value of Steemit inc's work is to be measured in Steem and not shares. At least that's my current logic - it could change depending on the long term capacity of Steemit inc. beyond Steem.

I actually went to Steemit.com and Steem.com looking for a company address, but didn't find one. When I clicked on 'contact' on steem.com I went to an xml file instead of a page.. lol
