Active users can't increase in many folds because of the big delay in registration. A lot of folks loose interest by the time there account is registered.

And I read the comments that it's not a problem because users who can't be patient and loose interest won't be real steemians are wrong because maybe if even 1/1000 of the users who don't wait out the account creation are excellent content creators, then steem misses out on the chance to grow big and be taken seriously.
