I am not an 'official' STEEM curator, but I am a curator. :)
I don't apply as 'official' curator because I am rather busy and thus there are days where I can curate a lot, but also other days on which I would clearly miss my own target. I think Steemians with more time and less STEEM power are the best chocie as 'official' STEEM curators ...

If I find exclusive STEEM content, I am willing to upvote it. So far the problem is that as a long time Steemian, most of my friends and also these great authors which I know are posting on both blockchains, which means that so far most of my upvotes are executed on both chains.
In future that may partly change:

• a) Because I get to know also great (maybe comparable new) authors who only post on STEEM.
• b) Probably a certain percentage of the completely new members will only use STEEM and thus produce 'STEEM exclusive' content.

Because of these necessary NEW users it is very important to make account creation as easy and fast as possible for everybody, also people without any blockchain experience.
As I think that's a rather important aspect, please allow me to tag you at this point @steemcurator01.
