I'm a professional photographer so for me it's easy to distinguish between a cute snapshot and a photograph that took some effort (someone searched for a great composition and/or edited in a fitting way). But I get what you mean - it's up to each curator to 'decide' of your snapshot of a dog is creative - and maybe today it is, tomorrow it isn't.
It's not that problematic that each curator will find different definitions of what is creative. Why? Because if one curator gives you an upvote and the other 9 all upvote something 'more' creative than there's still 'Proof of Creative' in the end :-)
Also, as the creative community grows, and our VP's get drained easily from all the awesome creative art, posts that are not super 'creative' will get less and less upvotes and eventually fade out.
Just enjoy the CCC you can earn right now and consider curating with it as well :-) Creatives are an important 'motor' in this cold and technical world, and we often find it hard to make a living because our skills are always undervalued and underpaid :-)
I like discussing these things and I see it as a huge learning curve we'll al go through :D Maybe CCC is just the start of a lot of spin-off Tribes that reward a very specific kind of creativity, like 'dog photographs taken on the street' :D
Cheers!
