I am not talking about freelancing in this though, they might not even need to post themselves. the company could potentially just create the account, add a place holder post and vote on it. Or a comment string.
There are so many various possibilities here but we concentrate heavily on the tip of the iceberg. It is going to be interesting how it progresses.
They could leave it blank but that leaving a perfect opportunity not used.
Imagine a call center that focused on text support. Customers leave there non-private information here for basic questions. Someone answers it and gets reward if the customer says it fixes there issue. If the customer was not a total pain in the butt they could get a small little upvote as well for following directions and not wasting peoples time. If they where they get a down vote that hurts there reputation over the long run and forces them to buy a new account to keep trolling or being overly aggressive towards customer support.
The blockchain itself is solving some of the set up costs to running certain services. There are so many different business applications.
If enough companies start to use steemit they can just take advantage of the skill sets that are already here form accounting, graphics designer, coding, consulting, and blogger, media manger and pay all with just upvotes posts that meet there need. Since we already have public and private keys I’m sure someone could set up so have posts that need to be encrypted be as such.
If anything our past posting/comments could be a way to see who to hire and who not. Which would be an issue for many since they can't go back and clean things up.
There is definitely a very wide assortment of applications that are going to come about and there is obviously already interest in blockchain for supply chain management solutions as it is a perfect medium for it. Going to get very busy in the blockchain world :)
