haha awesome :D

Yes, but how long can this go on?
Most accounts are created by @steem and each new account requires 15 Steem Power. Since @steem currently has only 432,015 SP the SP is sufficient for about 28800 additional accounts.

Also, how many will stay if they realize that the value of their vote is 0.0?

fast? not fast enough.
steemit exists now since about 2 years (happy birthday :D). other platforms had a multiple of those numbers after 2 years.
