EDIT... EDIT... EDIT
NOTICE: BASED ON THE REPLIES FROM @NED AND @STEEMMONSTERS, I AM MAKING THE FOLLOWING DISCLOSURE SO THAT I CLARIFY THINGS. I WILL LET THE READERS READ THE COMMENTS AND DRAW THEIR OWN CONCLUSIONS, BUT HERE IS THE EDIT.
The account that is shown here is in fact a real brand new steemit account. It was created through the use of RCs that are available to create new accounts in the future from dApps like 
. This is what a brand new "bare bones" Steemit account will be able to do. You will be able to make about 1 comment a day.
Steemit Inc will delegate RCs to new accounts created through them (but not through dApps) that are equal to roughly 1 post and 10 comments per day. This will only apply to accounts that are created from Steemit Inc directly. *Please note this is the best guess I can get from the people that seem to know, so it might be off a little but has been said by more than a few people that have been around.
If Steemit Inc does not change the formula for the calculation for comments, then new users will have essentially 4 levels of accounts.
1. Steemit Inc created accounts with about 1 post and 10 comments per day
2. Bare bones new accounts created by spending 3 steem or creating via RC's with the ability to comment 1 time a day.
3. User assisted new accounts that get delegations of either SP or RCs from users on the platform.
4. Self-funded new accounts where the person spends money to up the value in order to do more things like make comments and posts.
END OF EDIT
Wow... I am so stunned to find out what a newbie has to go through. You will be too if you pay attention.
I set up an account just to check it out for myself.
I created the account and it has 0 SP, but its open! (and I did pay to get it open btw, but the new policy is to burn the money instead of putting it into the account in the form of SP)
I made exactly:
one comment,
one edit of that same comment,
and followed one person.
This is what my Mana bar says now:
So in 3 days I can come back and make 3 more comments!
