very usefull when you want to see how was a website in the past!
The website web.archive.org could improve its user experience. But it's very usefull to verify how was your site (or your competitors websites in the past)
I don't know how they manage to store all those pages...
We develop websites in my company, and we couldn't remember how our site looked 8 years ago. web archive allowed us to go back to it. impressive!
