Today I ran across a noteworthy example of technological continuity. I was surprised!
A recent transition in hosting and registrar services caused me to review ancient web pages largely created in the mid to late 90s -- during the heyday of the personal web site. Among the dusty collection were a set of Internet Tutorials for my fellow family physicians.
Today I tried the applet. I had to enable pop-ups but, incredibly, it still works in Firefox 3 (I didn't try Safari or IE 7, no need to push my luck).
There's more continuity on the net than we typically assume.
