I think people are aiming to create the original geocities experience too: Examples: http://poeks.neocities.org/ http://skry.neocities.org/ http://jeremy.neocities.org/
That said, I don't care if people use it for Geocities parodies. I think Geocities sites are a lot more interesting than the bland, drab Facebook profile layout that everybody is forced into with no ability to change in any meaningful way.
