Floorcraft - or the lack of it - comes up frequently in conversation. As a follower I don't have the issues of having to deal with the swoopers and blockers and I do feel for my partner when his frustrations are spoiling his enjoyment of the dance. Sydneysiders have been told by many - including Jorge Dispari and Javier Rodriguez - that their floorcraft needs work.
We also need to work on our manners. A little consideration goes a long way on the crowded floor, but many dance like they drive, swooping into the safety zone cars have left on crowded highways, and stopping in no stopping zones because it suits them.
We also need to learn how to dance in a small space - so that when the milonga is 'crowded' (in our terms not as it is in BA) we are able to dance. A friend told me about this performance today. It is amazing, not just because of where the dance takes place, but because the dancers are clearly relishing the small space - and using it to its best advantage - and it is not an issue. You could do yourself a serious injury dancing in such a small space - but it is certainly something to aim for.
