Not really. It was certainly a way to do things. But it was less used than the current plethora of divs. Probably easier to understand programmatically, oddly.
I did too, but I don't remember it nesting to 10 that often. I grant that I likely just don't remember it. I recall most were like HN, embedding a couple of tables.
My argument, though, is that 10 is basically just getting started with how nested most div based layouts are. The new "grid" world is a bit of an improvement. Probably a large one, honestly.
