I'm still not too sure about Curie. The account sends out large payments to its "workers." Some accounts receive hundreds of SP very frequently from the Curie account.

Last I checked, the account sent out a couple hundred grand over the course of the year. I encourage anyone interested to use SteemSQL or something to collect all transfers out of these types of accounts and sum them. You will get an idea of the users that are profiting the most.

Curie doesn't seem very selfless. That doesn't mean I don't think it is useful, it just is paying its workers quite a lot.
