Our primary role is to run distributed servers worldwide that capture, process, validate and store the blocks of information from sites like this one to the block chain - a giant database, more or less, in laymans terms, or a ledger if you will, of all things steem that happen per user or account.

Our secondary role is to decide on block chain code change proposals via consensus. We also run price feeds to average our parameter choices into consensus on token prices, interest rates, bias, and other parameters affecting the price and performance of steem. like registration min SP investment per account and such.

Our tertiary and subjective role is to ensure the future of the platform via contributions of technical or social or financial nature via projects, communities, software contributions and investments in holdings, or growth or acceleration of user adoption, etc etc etc

And stuff, we do a lot of stuff.
