I experience #1, #2, #3, #4 and #5 by authoring posts.
I also experience #7 when a thumbnail catches my eye, and I am investing in Steem to offset any losses I'd incur if the Global Financial System and USD collapsed #8.
The decrease in authors was partly caused by Hardfork 20 and the need for Resource Credits. The low price of Steem played a greater role, but don't forget the RC requirement after Hardfork 20. @noisy @andararchy
I am personally very happy with @steemit @musing and the Steem blockchain!
