We entered in a new era in the way people use the net.
What it means for the old ways is that lots of websites are abandoned both by their owners and by the audience.
I don't know how many times I think of a fantastic domain name, check it and see it parked somewhere.
People did buy them, might have used them for a while or had an idea in the back of their heads but maybe it never took off.
Now, these domains and great potentials are simply asleep... Nothing is done with them.
