Wow, 10 years is a long time. Getting a design of mine in the CSSZenGarden was one of the biggest accomplishments of my life still to this day. I'm pretty sure that it's responsible for bootstrapping my career.
Same here. I was 16 when I had my design featured in CSSZenGarden in 2005 (it was this one http://www.csszengarden.com/?cssfile=185/185.css) and, although it did not bootstrap my career by any means, it has certainly been something I'm really proud of. Most front-end developers nowadays do not realize how important that website was back in the day.
Wow, I remember that header. Always thought it was insanely cool and jealous of people coming up with stuff like that.
