@Irishk,
Drawing a comparison between the hashmark and the swaztika that extends beyond the use of existing symbols for new purposes is pretty silly.
Obviously the hashmark symbol has its origins in twitter which fits the whole theme of Revolution vs Social Networking, but symbols have a way of taking on lives of their own and can attract entirely new meanings from large numbers of users who have no idea of the original intent.
It's also silly to assume sinister design here, and unnecessary. It's just the way people use and react to symbols.
I don't know if this hatchmark symbol is going to catch on but I would be surprised if it doesn't.
People (and particularly young people) want to have a very simply way to identify the like-minded in the larger group, and (more importantly I believe) send a simple signal that identifies them as one of the like-minded...or at least someone who wants to be accepted by the like-minded.
For that reason alone, some symbol is bound to emerge as
the symbol for OWC.
A secondary (albeit important) reason is marketing. People will stand to make a fair bit of money selling "stuff" that bears the semi-official symbol.
The marketers can't wait forever for the symbol to appear organically and so I'm sure they've already floated a number of trial balloons to see if any will catch on.
The hashmark is a natural. It can be stylized pretty heavily and in many different ways without losing its basic identity. It's aesthetically pleasing in that it is a pattern, and while it has some trace of familiarity, it is quite unique.
From a graphics design standpoint, tilting it on its side is brillant and is probably the way it will stick.
I would rush off to manufacture t-shirts and ball caps using this symbol if I didn't think there is already a large number of would-be competitors, well into it.
