The problem with vimeo and youtube is that there're way too many "test". And the "real" stuff is buried under the tons of visual garbage. People don't use their gear to create but to "test"...unfortunately.
My NX500 to be my second to my NX1 will be here tomorrow will have to get out and test it on a sleeping turtle and a shot of my parked car. I only wish it had a good slomo so i could capture some tree leaves blowing to.
I think one quite important reason of slomo on those small test shots on vimeo and youtube is to stabilize the panning. It is much easier to do a fluid handhold panning when you move a bit faster and then slow it down later in post. Also agree with DigitalEd, people getting their nice new cams and lenses (with stabilization in lens or body) and they shoot a flower without panning or a cup of tea with as shallow depth of field as possible...kind of pointless.... I say go out and swing that cam around....in whatever difficult lighting there is. Dont be afraid it does not look nice...thats kind of the point to see where its strong points are and where not.
