Actually curling is a very popular sport in a lot of places lol! It's played a lot in Scotland as well as a lot of others. Like golf however it may be better played than watched, talking of golf, that's a very big money maker, if it were in the Olympics (please no!) they would have the top names of golf playing. The Olympics seem to be about money, I think the 'popular' sports that bring the big names in such as basketball, tennis and athletics of course are the ones they will look to keep, regardless of TKDs worth or not (depending on opinions) I think it will be looked at in the light of how many tickets it will sell plus how televisual it is to entice the advertisers to buy time while it's on the television. A sport that doesn't attract the television cameras doesn't attract the advertisers.
