I think there is a problem is defining active user this way. Atleast for now, industry defines an active user as some one engaging with a network or using the network.You can argue viewing the network shall be counted as active. I think you should atleast discount unique or first time users and users from FB/searc/twitter etc. If some one daily browse steemit page for content, then he should be counted. These are industry standard matric used to compare networks, value them and spend money on such network (business model). We have to properly define the nunbers and then compare, then only we know how much the network is valued.
