I was going to say the same thing, and say that 1997 was the last time I saw anything using VRML, and that it was, indeed, way too early for "3D HTML" back then. No idea now that everyone has hopped on the 3D Movies/TV bandwagon in full force. Personally, I think it'd be difficult to make a plausible UI case for 3D, but that's me.

Exactly. My initial impression was: "whaaa.... is it 1995 again?". But hey, perhaps somebody does need it.

This might be a case of the dunning kruger effect in action. The blogger doesn't know enough about the web that he'd suggest a fancy new technology called 3d HTML without even knowing that it already exists.

How many people rely on inexperienced individuals like this for advice about the web when the advice giver him/herself doesn't even know their words are two decades late...

My first thought as well.

I'll never understand how anybody looked at all the amazing possibilities that were opening up due to the web in 1995 and thought "the next thing this really needs is a 3D environment!"... Oh well, I guess that was back when the 'Net was The Future and hackers were going to be able to kill you through your virtual reality headset.

In True Names, Neuromancer, and Snow Crash, the future user interface was 3D. Science fiction writers wouldn't lead us astray, would they?

BTW, if you really want declarative 3D, VRML has been replaced with X3D: http://www.web3d.org/x3d/
