they were interesting when people first started learning them because it was a new trick people could add to their bag and combo real well.
Now new riders think they look real cool and learn them before any other basics so you get these little groms that can do an infinite number of briflip combos but can't barely do any other trick. I've seen videos where the kid does a briflip late whip air and a flat doublewhip in the same video. Every single rider nowadays whores them, and not only do they just get played out, but front bris are quite possibly the most disgusting trick in the sport and a disgrace to front scooterflips which actually look good.
One last note is that people now are getting to the point where the only new tricks being done are new briflip combos rather than you know.. ACTUALLY coming up with a new trick. I try my best never to do briflips becuase I know I personally am not impressed in the least by them and I'd rather make my riding look good than show the world another buttercup. If I can help rid the world of briflips by keeping how-to videos or trick tips about them to a minimum, I will definitely do just that.
