"Having to see witnesses in the top ranks who define Steem as kind of failed/dead is way more negative for external investors than the 13 weeks powerdown period, I think."
Negative, but true and honest. And I prefer that over any kind of lie and bullshit. Okay, I am not a witness, especially not in the top ranks in any way. I am just/only a minnow, but I clearly see what is going on (and what is not) on the Steem blockchain.

"Look at what we all together have accomplished here."
More than 1.3 million Steem accounts, and the rapidly decreasing (dropping/falling) number of the daily active Steem accounts. Nowadays only about 30 000 Steem accounts active daily. This number was around 40 000 and 50 000 a few months ago. And even more before.
Many people are focusing only on their own blog posts, but only a few cares about other people's blog posts, this leads to a lack a real, human interaction, and to thousands of disappointed users. Nowadays I have 1008 followers, but most of them are inactive nowadays. They left Steemit (and the Steem blockchain) long (months) ago.
This is quite equal to a failed/dead project in my opinion.

"Please sell your house immediately for STEEM before the rocket will start. A way bigger house is waiting for you.
Thank me later."
Hahaha! :D
I currently do not have a house, but even if I currently would have one, I still would not sell it for Steem (or for any other thing). If I would have a house, then I would be satisfied/pleased/contended. I would happily live in it. I do not need a big house. And I do not want to be homeless either.

What you do for Steem is very good, but honesty (being honest) is also important in my opinion. I stil upvoted this blog post, and I call !trdo to support you for your works and efforts.
