I am one of those nostalgic for Alta Vista. I remember it as being one of the first really effective search engines, having previously just had Webcrawler - probably because AV used a lot of pattern logic (+“this” -that). They were also behind, or at least were early publishers of Babelfish - which was the first time I’d ever seen effective real time translation of any scale. So, they certainly made their mark on the late 90s.
That said, I haven’t even though about them since Google launched.
I suspect this won’t be the last thing Yahoo! kills this week.
