Or the fact that feet cubing is not very deep. It doesn't add much of a new dimension to solving a 3x3x3 as OH does, and the evolution of times that people are getting has basically stayed static since we first started holding the event.
Well, I have to disagree here. I find feet cubing to be very complicated to do, and I think it "adds much of a new dimension to solving a 3x3x3" just the same as OH does.
For feet solving, you have to change the way you "hold" the cube, the angle at where you look at it, the way you make turns, new algs, etc. I wonder how people don't get confused in the middle of a long PLL in which they turn the cube a few times and move 2 or 3 different layers.
As for the evolution, look here: (I'm sure you already did, but probably not everybody)

I think going from 5 minutes to 30 seconds is quite good.
Take OH, for example. It went from ~45 to 12.
I'm not a big fan of feet solving, specially because of the logistics (having to move the timers out/back to the tables, moving chairs and such) and because lot of non-fast people do it, at least here. I'd probably be a little happier if it became unofficial, but I'm not sure it should.
The media here in Brazil seems to LOVE feet cubing. It's almost always a headline whenever they cover a competition. I don't know how many people find it gross/disgusting or damaging to the speedcubing image, but as someone already said, we don't look exactly "serious" turning our stupid little cubes real fast, traveling around and competing for no good prizes. I personally don't think it affects our image in a bad way.
