i have found a very uniqe web site which is www.arhcive.org (http://www.archive.org). Probably most of you already knew. it is a way back machine. When you type something, this site find the old versions of the site. When I entered yahoo.com, I undestood how web tech changed quite a bit in just a few years.

Apos, you have a typo in the link; it should be www.archive.org not arhcive! :)

And yes, as you expected it's been mentioned here before -- as a search shows: http://webhostingtalk.com/search.php?action=showresults&searchid=577325&sortby=lastpost&sortorder=descending
