Uh, no. Let's add more stuff, not take stuff away.
Are you sure? Football, tennis... Golf, baseball...
Golf was tried and dropped already, along with several other sports. You can't just keep adding stuff like a kid in a candy store. The Olympics is already a financial and logistical nightmare. Any additions have to very carefully considered, and some things may be dropped from time to time.
I'm old enough to remember when rhythmic gymnastics was introduced to the Olympics. At the time a lot of people thought "WTF is this shit?". I still think that way about this particular event. I'd prefer to see it dumped. I think the Olympics would be better for the change. That's my opinion, like it or not.
Note that I'm not against change per se. For example, I think the introduction of BMx is fine. It has a great bread and circuses element to it. Equipment costs are reasonable. The riders are every bit as fit as the velodrome cyclists, and arguably more skilled. If the Olympics organisers find it necessary to rationalise cycling, IMO keeping BMx and dropping some of the more idiotic velodrome events (ie: keirin) would make sense.
I'm a sailing fan, and the classes used in the Olympics have changed over time. I don't mind if they change again. I honestly can't see the point of having the 470 and the 49er. Both are two handed trapeze classes, but IMO the 49er is a far superior class in terms of spectator appeal, and it eats 470's for breakfast in terms of performance. Despite the fact the Australia has just picked up gold in both classes, I'd be fine with the 470 being dropped.
I'm a rowing fan too, and I wouldn't mind if rowing was rationalised either. Most of the sweep classes really only exist because traditionally the eights have been seen as the pinnacle of competitive rowing, and the other sweep classes are seen as trainers for the eights. They're less effficient than the sculls though, and worse for the athlete's bodies. It's actually illegal for young rowers to train in sweep classes, because the bad effects on their bodies are recognised.
IMO the quad sculls are far more elegant to watch than the eights, and they are almost as fast. They're cheaper to build and easier to transport. It'll never happen, purely because of tradition, but if the only Olympic classes were single, double and quad sculls I think that would be fine. It'd be a good match for the kayaks in terms of classes, and the races could be run over a variety of distances like the kayaks.
