Archiving Like Crazy

Archive.org

From reading that article and playing around with archive.org, it's really fascinating to see the progression of sites across the internet. It would seem that a few common things are happening across web sites in general:

Use of Search throughout websites
User Interfaces have improved dramatically
Transactions are easier, smoother - eg. one-click is pervasive on most sites
Use of flash, movies, etc. has grown as broadband/wifi use is more prevalent

While it is scary that someone has the ability to check your websites history and could potentially use that information against you, it can also aid you in the development of new features and minimizing mistakes from the past.
