As someone who made websites in the geocities days, it's amusing to me that one of the tell-tale signs of a Gemini-built website is a MARQUEE! I genuinely love that the marquee tag is making a come-back due to what I can only imagine was someone on the Google team who loves it too and decided to put that into the system prompt when websites are requested.
Honestly? That is the real reason.
I miss the era when the web was raw, weird, and unpolished. Modern UI feels too sanitized and corporate.
The "Neo-Brutalist" label is just a convenient modern excuse to bring back the fun chaos of the Geocities days without looking outdated. Glad it hit the nostalgia nerve!
