This is all very interesting and I tried to read all the comments but there are obviously too many. So I am not sure if anyone mentionned something close to what I'd like to bring up.

First, thanks @steemitblog for the explanations and the communication, however I assume you realise not everyone fully understands the technicity of HF20. Plus there is this non-negligeable amount of users who don't seem so happy about it.

Pardon me if I am wrong and I wish to be corrected but as a "simple" content creator, my point is that I haven't read anything about our "condition". It all seem about costs/scaling and while I confidently let this to the developers, I'd be happy to know (in vulgar language if possible), what exactly will improve for creators like artists, writters, musicians, bloggers, vloggers etc... 

I mean, I think many of us are looking for an alternative to mainstream networks which were a great way so far to promote our creations or businesses while connecting and exchanging with humans all around the globe (ok, Steemit does a good job with that last sentence, I did meet and discover AWESOME stuff here).

Genuine users I am sure want less spam and more than mainly posts about how to become rich with cryptos. I do read indeed that the update also focuses on spam but what is being made to attract new (*and if possible famous*) content creators?

For instance; that is a detail but lot of musicians could be interested. Unfortunately the lack of a calendar gives most of them cold feet (I imagine that this will probably rely on the creation of an external app but I am still asking ...)..

On my side I am actively trying to invite new users and I read that HF20 is going to make the creation of accounts easier but in what does it help in actually *attracting* new users in signing up? And then to keep them active? Over the few people that I succeed to make register, none have been active, there must be reasons for that. Well, it is known that many newcomers are discouraged first by the complexity and then by the fact that it looks very hard (ok ... *It's supposed to be hard. If it were easy, everyone would do it.* -Agree but...) to reach a decent level of power without spending all your time on the platform. I am not going to point all the flaws of Steemit, but there should really be something else than the rewards to attract people, I know it's the actual content quality that should do that. But this quality can moslty be reached by bringing more genuine users rather than just profiters (money obsessed people), or?

Is how attractive the network is, left to "let's see how it'll go"?
Or are there actions done to increase that attractivity?

I did read somewhere that @curie and other curators were, despite their huge role in helping minnows, not enough. Indeed, haven't seen any new. 
More scary, why did truly supportive accounts like @ocd and @slothicorn become inactive?

At the moment, minnows rely too much on the good willing of whales to get decent upvotes but for most of us, I believe the hope is to have a community that could sustain itself (upvoting each others) without depending of whales, or at least, less. Increasing rewards for real qualitative content seems one of the biggest deal.

My worst vision is that the system creates more and more inequality, that we all end up voting only for content that is sure to bring money (in other words, always the same accounts) and discard content that we like but don't bring $. And I am not mentionning the obvious worst, the crash! :D

Maybe issues like that are planned to be worked on in the future and that the most important at the moment is indeed, to make the platform sustainable, I'd understand but again, shouldn't we be reassured that this is taken in consideration? And even if it gets stable and sustainable technically and costly, getting more user onboard should be a priority.

It is totally possible that regarding my noobism I am missing or misunderstanding that *there are* incentives regarding those issues, I'd then ask to pardon my ignorance but would please still someone light my lantern?

Because really, if this place is *really and only* about money, the best content and comments will always look fake and boring. I am afraid it'll never attract much more genuine creators. 
Again, as "simple" creators who are not technicians, we need to be more listened to. We might be unaware of how works the motor but our opinion as drivers does count.

Thank you all and sorry for my rather negative and inquisitive tone, be assured I still have faith and looking forward what's coming up!!!
