Yes. and we did just that yesterday, the first one we are following is @ocbd. All those accounts you mentioned are doing a great job curating ( I need to up my quality and post at the right time for them to find me though LOL)

Indeed steem has some great people looking out for good content. like @broncnutz who just voted my appics post:)

I'd definitely love to learn a thing or two on how they organize their curation and the criteria etc. though following their trail is the easy and effective way, manually curating is something we want to focus on as well. even with all these curation accounts there are still people being "missed" that have good quality content. There are many content creators and not so many curators.
