It hasn't changed very dramatically. A lot of newer players compared to back in the day.
From above, people concentrate on making things look good rather then making them work. Not always true, but definitely in many cases.
A lot of the older players don't play much, and a good amount of the players from 2010 aren't playing because they found the forums and, well, you know what happens after that.
I think that compared to the older moves, a lot of players aren't prepared for them. For example if you use some oldschool move in wushu, unless your playing someone whos actually good at wushu they don't know how to counter it. This more or less carries over to other mods. But there is a handful of people who are quite good that you see around a lot. You'll find them soon enough.
