After the fork it will be possible to instantly create accounts with 0 SP in them. But they will be limited and distributed by stake. We don't know yet how that will shake out, but my best prediction is that the dApps that have big delegations from Steemit will be able to do account signups and they will take them all before they get down to regular users.
And we don't know how any of them will choose to do that. It will probably be relatively easy to get new accounts through at least one of them, but that's not guaranteed.
Dapps like @actifit, @dlike, and @steepshot need the ability to offer the greatest user experience if they want to start growing their user base. I dunno how are we going to start competing more seriously with the social media big fishes, I think that Steemit has the community and the platform to do that and the launch of SMT can be the initial step in that direction. But we need more boldness coming from the developer team, or it is that they have another horizon in mind. I yet don fully understand where are they leading this project.
Thank you for your time.
