Browsing the net today... I stumbled onto a great site I'd forgotten about. It's called The Wayback Machine, and since I stopped by there last, they've given it its own domain name: archive.org.
Basically, the Wayback Machine stores web archives.
Do a search there - for Jalpuna.com, for example, and you can see what Jalpuna looked like on March 17th, 2004. (pretty crappy - I was just getting started) The site was looking much better by September 25th.
Or how about CNN on 9/11/2001.
Here's a fun one: Apple, on October 22nd, 1996:
Apple announced a new version of the GeoPort Telecom Adapter Kit, increasing modem speed to 28.8 Kbps
Damn, I need to get me one of those!
