Post-Presentation Post

I missed/didn't adequately talk about some things in my presentation.
Someone's card said they still weren't sure about the difference between Parkour and Free Running. The thing is people in the culture have trouble articulating themselves. The generally accepted thing is that in Parkour every movement you do needs to be efficient and help you get from point A to point B.
I think there might have been some confusion when I said that acrobatic moves are Free Running since some people might consider the Parkour moves acrobatic. But I am referring to things like flips and moves you would find in Tricking (Another similar type culture/activity). Jumping onto a wall and doing a flip off of it is not the most efficient way to get over the wall. Of course some people argue that these sorts of moves improve your proprioception and coordination so there is nothing wrong with them, but then the other side argues back that that doesn't make it Parkour. You can do those things, but don't call it Parkour. But then the people more liberal with their definitions say that Parkour is any kind of attempt to move through a space. That is why these discussions span many pages and many topics at the forums. Some argue that Parkour is the ideology and not the actual movements, and those are the ones who even more liberal. The guy who organized the meet-up probably fit in that category.
One thing I forgot to mention was the commercialization. The main thing I noticed was shoes. Given the types of things the traceurs have to do, it is important that they have shoes that make this as easy/safe as possible (running up or along walls). There is a market for shoes that have very good grip. When I was at the meet I heard a lot of talk about shoes. Style wise there isn't much I noticed, except sweatpants. Most people were wearing sweatpants. But like the shoes this was functional, as they were looking for clothes that gave them a large range of motion. One guy was wearing a t-shirt that said "Parkour" on it though if that counts as commercialization.
Anti-competition wise I found that MTV actually has a show called Ultimate Parkour Challenge, and the forums were pretty opposed to it being presented as a competition. Also on the site I see they have lots of links to videos of acrobatic moves which doesn't help the confusion.
