Busking has morphed with the times hasn't it? Once it was defined as the experience you had right there, right then - with possibly a self-promotion element like a business card for gigs or, more recently, maybe a CD.
Now, of course, it's *potentially* as big as the web - and a degree of culpability lies with this very blog.
At the same time, there seems to me a shift in buskers' material. There has always been real talent on the streets, but I'm sensing a move away from the personal with more tailoring towards a broader audience. There's starting to be slicker product out there - what's next for busking?
