...that once an area is discovered by 'squares' who push prices up, the artists and immigrants get priced out and the area starts to lose the vibrancy that attracted the squares in the first place!
This happened in Fitzroy, in Melbourne. Now the 'scene' is about 10ks north.
I'm not sure if that's entirely true. The colonists tend to be design agencies (at least in places like Hoxton and Shoreditch in London), or other creative companies. It'll be less cutting edge or experimental, and the artists will complain that they're forced to move further out as rents and prices increase.
And, of course, old timers will complain it's not as good as it used to be.
That said, I can see where Luce.Rocks is coming from. Somewhere like Fitzroy is more interesting than the ultra-prime suburbs like Toorak.
